Check Digit Verification of cas no

The CAS Registry Mumber 25445-03-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,5,4,4 and 5 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 25445-03:
(7*2)+(6*5)+(5*4)+(4*4)+(3*5)+(2*0)+(1*3)=98
98 % 10 = 8
So 25445-03-8 is a valid CAS Registry Number.

Lewis acid-catalyzed, copper(II)-mediated synthesis of heteroaryl thioethers under base-free conditions

Dai, Chao,Xu, Zhaoqing,Huang, Fei,Yu, Zhengkun,Gao, Yan-Feng

experimental part, p. 4414 - 4419 (2012/06/18)

A Lewis acid (AgI, NiII, or FeII) catalyzed, CuII-mediated thiolation reaction between heteroarenes and thiols was achieved with good yield under base-free conditions. DMSO could serve as an effective methylthiolation reagent for the synthesis of heterocyclic methyl thioethers.
