Check Digit Verification of cas no

The CAS Registry Mumber 1607830-35-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,0,7,8,3 and 0 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1607830-35:
(9*1)+(8*6)+(7*0)+(6*7)+(5*8)+(4*3)+(3*0)+(2*3)+(1*5)=162
162 % 10 = 2
So 1607830-35-2 is a valid CAS Registry Number.

Synthesis of GABOB and GABOB-based chiral units possessing distinct protecting groups

Ivsic, Trpimir,Dokli, Irena,Rimac, Ana,Hamersak, Zdenko

, p. 631 - 638 (2014/02/14)

In addition to the varied biological activity of GABOB (4-amino-3- hydroxybutanoic acid), the structure of its protected derivatives makes them interesting chiral intermediates for the synthesis of more complex compounds. A stereoselective route to GABOB derivatives with three different protecting groups is presented, using anhydride desymmetrization as a chirality-inducing step. Selective removal of the protecting groups gave compounds with a free carboxylic acid or hydroxy group. Removal of all of the protecting groups allowed GABOB to be isolated in good yield and with excellent ee. A stereoselective route to GABOB (4-amino-3-hydroxybutanoic acid) derivatives with three different protecting groups is presented. Selective deprotection produced diprotected chiral building blocks with a free carboxylic acid or hydroxy group. Removal of all the protecting groups allowed GABOB to be isolated. Copyright
