Check Digit Verification of cas no

The CAS Registry Mumber 133787-11-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,3,7,8 and 7 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 133787-11:
(8*1)+(7*3)+(6*3)+(5*7)+(4*8)+(3*7)+(2*1)+(1*1)=138
138 % 10 = 8
So 133787-11-8 is a valid CAS Registry Number.

Synthesis of α,ω-Diamino Acids via Amidocarbonylation Reaction: Novel Synthesis of Lysine, Ornithine, and Their Analogs

Amino, Yusuke,Izawa, Kunisuke

, p. 613 - 619 (2007/10/02)

α,ω-Diamino acid derivatives, such as lysine and ornithine, were synthesized via amidocarbonylation (cobalt-catalyzed formation of N-acyl α-amino acid from aldehyde, amide and carbon monoxide) of ω-(phthalimido)alkanals in good yield.The phthalimido group
