Check Digit Verification of cas no

The CAS Registry Mumber 1005348-40-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,0,5,3,4 and 8 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1005348-40:
(9*1)+(8*0)+(7*0)+(6*5)+(5*3)+(4*4)+(3*8)+(2*4)+(1*0)=102
102 % 10 = 2
So 1005348-40-2 is a valid CAS Registry Number.

Bis(heterocumulenes) derived from the 1,4-diphenyl-1,3-butadiyne framework. Synthesis of three new classes of axially chiral biheteroaryls

Alajarin, Mateo,Bonillo, Baltasar,Vidal, Angel,Bautista, Delia

, p. 291 - 294 (2008/09/17)

(Chemical Equation Presented) Bis(ketenimines) and bis(carbodiimides) derived from 1,4-bis(2-aminophenyl)-1,3-butadiynes via two independent bi-radical cyclizations provided, respectively, axially chiral bis(benzocarbazoles) and bis(quinindolines). Mixed biheteroaryls, consisting of benzocarbazole and quinindoline units, have been also prepared by a slightly modified strategy.
