Check Digit Verification of cas no
The CAS Registry Mumber 122640-83-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,2,6,4 and 0 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 122640-83:
(8*1)+(7*2)+(6*2)+(5*6)+(4*4)+(3*0)+(2*8)+(1*3)=99
99 % 10 = 9
So 122640-83-9 is a valid CAS Registry Number.

Syntheses and characterization of cis- and trans-dicyclohexyl-3,3′ ,4,4′-tetracarboxylic acids and their dianhydrides
Shiotani, Akinori
, p. 179 - 188 (2007/10/03)
cis- and trans-Dicyclohexyl-3,3′ ,4,4′-tetracarboxylic acid and their dianhydrides were prepared from tetramethyl dicyclohexyl-3,3′ ,4,4′-tetra-carboxylates by hydrolysis and subsequent dehydration. The trans dianhydride 2b was found to be sensitive to te
