Check Digit Verification of cas no

The CAS Registry Mumber 1642135-32-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,4,2,1,3 and 5 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1642135-32:
(9*1)+(8*6)+(7*4)+(6*2)+(5*1)+(4*3)+(3*5)+(2*3)+(1*2)=137
137 % 10 = 7
So 1642135-32-7 is a valid CAS Registry Number.

Copper-catalyzed synthesis of 2-aminobenzothiazoles from carbodiimide and sodium hydrosulfide

Zeng, Weilan,Dang, Pan,Zhang, Xiaoyun,Liang, Yun,Peng, Caiyun

, p. 31003 - 31006 (2014/08/05)

An efficient copper-catalyzed method for the synthesis of a variety of 2-aminobenzothiazoles has been developed. The reaction proceeded from carbodiimide and sodium hydrosulfide via a tandem reaction in the presence of copper(ii) trifluoromethanesulfonate to afford the corresponding 2-aminobenzothiazole derivatives in good to perfect yields. This journal is the Partner Organisations 2014.
