Check Digit Verification of cas no

The CAS Registry Mumber 878274-47-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,7,8,2,7 and 4 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 878274-47:
(8*8)+(7*7)+(6*8)+(5*2)+(4*7)+(3*4)+(2*4)+(1*7)=226
226 % 10 = 6
So 878274-47-6 is a valid CAS Registry Number.

Synthesis of the indene, THF, and pyrrolidine skeletons by lewis acid mediated cycloaddition of methylenecyclopropanes with aldehydes, N-tosyl aldimines, and acetals

Shao, Li-Xiong,Xu, Bo,Huang, Jin-Wen,Shi, Min

, p. 510 - 517 (2008/09/20)

Methylenecyclopropanes (MCPs 1) react with aldehydes, N-tosyl aldimines, and acetals to give the corresponding indene. THE and pyrrolidine cyclo-addition products in the presence of BF2·'OEt2 under mild reaction conditions. Some special transformations of MCPs 1 with aldehydes have been reported in this paper. A plausible reaction mechanism has been discussed, which is based on a deuterium-labeling experiment and the Prins-type reaction mechanism.
