Check Digit Verification of cas no

The CAS Registry Mumber 90280-94-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,2,8 and 0 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 90280-94:
(7*9)+(6*0)+(5*2)+(4*8)+(3*0)+(2*9)+(1*4)=127
127 % 10 = 7
So 90280-94-7 is a valid CAS Registry Number.

PHOTODIMERIZATION OF 1,4-DICINNAMOYLBENZENE CRYSTAL VIA A TOPOCHEMICAL PROCESS

Hasegawa, Masaki,Nohara, Masao,Saigo, Kazuhiko,Mori, Toru,Nakanishi, Hachiro

, p. 561 - 564 (2007/10/02)

1,4-Dicinnamoylbenzene crystals photodimerize readily via a double cycloaddition into the corresponding tricyclic dimer, which consist of two cyclobutane rings and a macro ring bridged by two phenylene linkages.
