Check Digit Verification of cas no

The CAS Registry Mumber 680597-57-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,8,0,5,9 and 7 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 680597-57:
(8*6)+(7*8)+(6*0)+(5*5)+(4*9)+(3*7)+(2*5)+(1*7)=203
203 % 10 = 3
So 680597-57-3 is a valid CAS Registry Number.

Photochromic dihetarylethenes 19. * Synthesis of 1, 2-dihetarylethenes on the basis of thieno[3,2-b]pyrroles linked by a maleimide bridge

Krayushkin,Yarovenko,Semenov,Zavarzin,Martynkin,Uzhinov

, p. 1814 - 1816 (2003)

New photochromic 1,2-dihetarylethenes containing maleimide-bridged thieno[3,2-b]pyrrole fragments with aliphatic and aromatic substituents at the nitrogen atom were synthesized.

Photochromism of thienyl-containing dihetarylethenes with five-membered cyclic bridges

Barachevsky,Strokach,Krayushkin

, p. 181 - 186 (2007/10/03)

Spectral-kinetic characteristics of a number of new photochromic dihetaryethenes with different five-membered cyclic bridges are measured and discussed. It was shown that these characteristics depend on a bridge structure as well as a nature of substituents in the thienyl fragments.
