Check Digit Verification of cas no

The CAS Registry Mumber 1174761-19-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,7,4,7,6 and 1 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1174761-19:
(9*1)+(8*1)+(7*7)+(6*4)+(5*7)+(4*6)+(3*1)+(2*1)+(1*9)=163
163 % 10 = 3
So 1174761-19-3 is a valid CAS Registry Number.

One-pot synthesis of α-amino acids from imines through CO2 incorporation: An alternative method for strecker synthesis

Mita, Tsuyoshi,Chen, Jianyang,Sugawara, Masumi,Sato, Yoshihiro

, p. 1393 - 1396 (2011)

Itas a gas: A novel one-pot process for the synthesis of α-amino acids from imine equivalents using CO2 gas as a carbon source has been developed. This reaction was made possible by the reagent combination of TMSSnBu3 and CsF (see scheme). Three successive reactions (imine formation, stannylation, and carboxylation) proceeded in the same flask under these conditions to give products in up to 79 % yield. Boc=tert-butoxycarbonyl, TMS=trimethylsilyl.
