Check Digit Verification of cas no

The CAS Registry Mumber 81913-83-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,9,1 and 3 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 81913-83:
(7*8)+(6*1)+(5*9)+(4*1)+(3*3)+(2*8)+(1*3)=139
139 % 10 = 9
So 81913-83-9 is a valid CAS Registry Number.

Reversible Photodimerization of Some Butadiene Derivatives in Solid State

Swamy, Ramachandra, H.,Ramamurthy, V.,Rao, C. N. R.

, p. 79 - 82 (2007/10/02)

Photodimerization of a series of butadiene derivatives in the solid state has been investigated to explore the possible occurence of reversible photochromy.The study underscores the importance of topochemical factors in solid state organic reactions.
