Check Digit Verification of cas no

The CAS Registry Mumber 434284-31-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,3,4,2,8 and 4 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 434284-31:
(8*4)+(7*3)+(6*4)+(5*2)+(4*8)+(3*4)+(2*3)+(1*1)=138
138 % 10 = 8
So 434284-31-8 is a valid CAS Registry Number.

Synthesis and isomerization of tricyclo[7.3.1.02,7]tridecen-13-ones

Rostovskaya,Vysotskaya,Grigorchuk,Vysotskii

, p. 1414 - 1417 (2007/10/03)

Dehydration of 2-hydroxy-8-R-tricyclo[7.3.1.02,7]tridecan-13-ones (R = H, Me, Ph) effected by various reagents provided 8-R-tricyclo[7.3.1.02,7]tridecen-13-ones with different positions of the double bond. In the presence of phosphoric acid arise isomers with the double bond in 2(3) position, a mixture of hydrochloric and acetic acid primarily affords isomers with the double bond in 2(7) position that further migrates into 7(8) position at R = Me, Ph.
