Check Digit Verification of cas no

The CAS Registry Mumber 90407-90-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,4,0 and 7 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 90407-90:
(7*9)+(6*0)+(5*4)+(4*0)+(3*7)+(2*9)+(1*0)=122
122 % 10 = 2
So 90407-90-2 is a valid CAS Registry Number.

VALENCE ISOMER INTERCONVERSION OF NORBORNADIENES AND QUADRICYCLANES HAVING AN ACYL GROUP

Hirao, Ken-ichi,Yamashita, Asami,Ando, Akira,Hamada, Tatsuo,Yonemitsu, Osamu

, p. 2913 - 2916 (2007/10/02)

As a model for light energy conversion, various acylnorbornadienes and their corresponding valence isomers acylquadricyclanes have been prepared.Among these (19) and (31) were found to be the best pair for the purpose because of the visible light absorption of (19), a high quantum yield for its photocycloaddition and a rapid and complete reversion of (31) to (19) with an acid catalyst.
