Check Digit Verification of cas no

The CAS Registry Mumber 1242169-02-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,4,2,1,6 and 9 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1242169-02:
(9*1)+(8*2)+(7*4)+(6*2)+(5*1)+(4*6)+(3*9)+(2*0)+(1*2)=123
123 % 10 = 3
So 1242169-02-3 is a valid CAS Registry Number.

Synthesis of benzoxazole and benzimidazole derivatives via ligand-free copper(I)-Catalyzed cross-coupling reaction of o-halophenols or o-haloanilines with carbodiimides

Shen, Guodong,Bao, Weiliang

supporting information; experimental part, p. 981 - 986 (2010/06/15)

A novel and efficient synthesis of benzoxazole and benzimidazole derivatives via a ligandfree, copper(I)-catalyzed, one-pot cascade process has been developed. A variety of carbodiimides coupled with o-halophenols or o-haloanilines to give the products in moderate to excellent yields under the mild conditions.
