Check Digit Verification of cas no

The CAS Registry Mumber 1127902-71-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,2,7,9,0 and 2 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1127902-71:
(9*1)+(8*1)+(7*2)+(6*7)+(5*9)+(4*0)+(3*2)+(2*7)+(1*1)=139
139 % 10 = 9
So 1127902-71-9 is a valid CAS Registry Number.

Asymmetric synthesis of cyclic cis -β-Amino acid derivatives using sulfinimines and prochiral weinreb amide enolates

Davis, Franklin A.,Theddu, Naresh

experimental part, p. 3814 - 3820 (2010/08/22)

Figure presented Cyclic cis-β-amino Weinreb amides, valuable building blocks for the asymmetric synthesis of cyclic β-amino acids derivatives, are readily prepared via ring-closing metathesis of sulfinimine-derived N-sulfinyl β-amino diene Weinreb amides.
