618448-72-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 618448-72-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,1,8,4,4 and 8 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 618448-72:
(8*6)+(7*1)+(6*8)+(5*4)+(4*4)+(3*8)+(2*7)+(1*2)=179
179 % 10 = 9
So 618448-72-9 is a valid CAS Registry Number.

Disodium Salts of Pseudoephedrine-Derived Myers Enolates: Stereoselectivity and Mechanism of Alkylation

Zhou, Yuhui,Keresztes, Ivan,Macmillan, Samantha N.,Collum, David B.

supporting information, p. 16865 - 16876 (2019/11/03)

Pseudoephedrine-derived dianionic Myers enolates were generated using sodium diisopropylamide (NaDA) in THF solution. The reactivities and selectivities of the disodium salts largely mirror those of the dilithium salts but without the requisite large exce

Asymmetric synthesis of four diastereomers of 3-hydroxy-2,4,6-trimethylheptanoic acid: Proof of configurational assignment

Turk, Jeffrey A.,Visbal, Gonzalo S.,Lipton, Mark A.

, p. 7841 - 7844 (2007/10/03)

Four unique diastereomers of 3-hydroxy-2,4,6-trimethylheptanoic acid-(2R,3R,4R), (2S,3R,4R), (2S,3R,4S), and (2R,3R,4S)-the fatty acid component of callipeltin A and D, have been synthesized from commercially available (+)- and (-)-pseudoephedrine propion
