Check Digit Verification of cas no

The CAS Registry Mumber 1284306-20-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,8,4,3,0 and 6 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1284306-20:
(9*1)+(8*2)+(7*8)+(6*4)+(5*3)+(4*0)+(3*6)+(2*2)+(1*0)=142
142 % 10 = 2
So 1284306-20-2 is a valid CAS Registry Number.

, p. 517 - 519 (2010)

A novel synthetic route to chiral β-amino acid derivative has been developed by a Grignard reaction of 2,4,5-trifluo- rophenyl magnesium bromide with the Weinreb amide derivative of L-aspartic acid. The aspartic equivalent was synthesised from L-aspartic
