Check Digit Verification of cas no

The CAS Registry Mumber 249564-42-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,4,9,5,6 and 4 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 249564-42:
(8*2)+(7*4)+(6*9)+(5*5)+(4*6)+(3*4)+(2*4)+(1*2)=169
169 % 10 = 9
So 249564-42-9 is a valid CAS Registry Number.

Thermal hetero [3 + 2] cycloaddition of dipolar trimethylenemethane to N-sulfonyl and N-acyl imines. Synthesis of γ-amino acid derivatives

Yamago, Shigeru,Yanagawa, Masao,Nakamura, Eiichi

, p. 879 - 880 (1999)

Thermal hetero [3 + 2] cycloaddition reaction of a dipolar trimethylenemethane 2 with an N-acyl or N-tosyl imine gives an α-methylene-γ-pyrrolidone acetal 4 in high yield, which upon hydrolysis affords a γ-amino acid derivative.
