Check Digit Verification of cas no

The CAS Registry Mumber 1199943-77-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,9,9,9,4 and 3 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1199943-77:
(9*1)+(8*1)+(7*9)+(6*9)+(5*9)+(4*4)+(3*3)+(2*7)+(1*7)=225
225 % 10 = 5
So 1199943-77-5 is a valid CAS Registry Number.

Copper(I)-catalyzed cascade synthesis of 2-substituted 1,3-benzothiazoles: Direct access to benzothiazolones

Murru, Siva,Mondal, Pravat,Yella, Ramesh,Patel, Bhisma K.

experimental part, p. 5406 - 5413 (2010/02/28)

An efficient cascade process for the preparation of 2-substituted 1,3-benzothiazoles directly from 2-haloaryl isothiocyanates and O or S nucleophiles by a Cu-catalyzed, intramolecular, C-S bond formation has been developed. This cascade method is viable f
