127041-69-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 127041-69-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,7,0,4 and 1 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 127041-69:
(8*1)+(7*2)+(6*7)+(5*0)+(4*4)+(3*1)+(2*6)+(1*9)=104
104 % 10 = 4
So 127041-69-4 is a valid CAS Registry Number.

A facile approach to trans-4,5-pyrrolidine lactam and application in the synthesis of nemonapride and streptopyrrolidine

Huang, Wei,Ma, Jing-Yi,Yuan, Mu,Xu, Long-Fei,Wei, Bang-Guo

, p. 7829 - 7837 (2011/10/12)

An efficient approach to trans-4-hydroxylpyrrolidine lactams 1 starting from amino acid is described. The utility of this method has been demonstrated in the synthesis of antipsychotic nemonapride 3 and antiangiogenic streptopyrrolidine 4. Compared four s

CYCLIC AMINE COMPOUND

Page/Page column 119-120, (2010/11/25)

A compound represented by the formula (I) or a salt thereof: (I) wherein the ring A represents a 5- to 8-membered ring which may have additional substituent besides R6, R7 and R8; R1 represents an electron-attracting group; R2, R3, R4 and R5 independently represent a hydrogen atom, a halogen atom, a group attached through a carbon atom, a group attached through a nitrogen atom, a group attached through an oxygen group, or a group attached through a sulfur atom; R6 represents a halogen atom, a group attached through a carbon atom, a group attached through a nitrogen atom, a group attached through an oxygen group, or a group attached through a sulfur atom, and R7 represents a cyano group, a nitro group, an acyl group which may have a substituent, a carboxyl group which may be esterified or amidated, or a hydrocarbon group which may have a substituent, or R6 and R7 together with a carbon atom to which they are attached may form a ring which may have a substituent; and R8 represents a hydrogen atom, a halogen atom, a group attached through a carbon atom, a group attached through an oxygen atom, or a group attached through a sulfur atom. The compound or salt has an excellent androgen receptor modulating effect, and is useful for the prevention/treatment of hypogonadism, partial androgen deficiency in aging male, decline in physical strength, cachexia, osteoporosis and the like.

Diastereoselective addition of allyl reagents to variously N-monoprotected and N,N-diprotected L-alaninals

Gryko, Dorota,Jurczak, Janusz

, p. 2705 - 2711 (2007/10/03)

Diastereoselective C3-elongation processes of N-Boc-, N-Z-, N-Bn-N-Boc-, and N-Bn-N-Z-L-alaninals (Boc = 'BuOCO, Z = PhCH2OCO, Bn = PhCH2) using various allyl reagents, such as allyl bromide in the presence of Zn/aqueous N
