Check Digit Verification of cas no

The CAS Registry Mumber 915237-97-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,1,5,2,3 and 7 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 915237-97:
(8*9)+(7*1)+(6*5)+(5*2)+(4*3)+(3*7)+(2*9)+(1*7)=177
177 % 10 = 7
So 915237-97-7 is a valid CAS Registry Number.

Reaction of ene-bis(phosphinylallenes): [2+2] versus [4+2] cycloaddition

Kitagaki, Shinji,Okumura, Yuki,Mukai, Chisato

, p. 10311 - 10320 (2007/10/03)

Reaction of ene-bis(phosphinylallenes), derived from ene-bis(propargyl alcohols) and chlorodiphenylphosphine, was investigated. Benzene-bridged bis(phosphinylallenes) exclusively gave intramolecular [2+2] cycloadducts in the presence of dimethyl fumarate
