Check Digit Verification of cas no

The CAS Registry Mumber 1236003-87-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,3,6,0,0 and 3 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1236003-87:
(9*1)+(8*2)+(7*3)+(6*6)+(5*0)+(4*0)+(3*3)+(2*8)+(1*7)=114
114 % 10 = 4
So 1236003-87-4 is a valid CAS Registry Number.

Organophosphine-free copper-catalyzed isothiocyanation of amines with sodium bromodifluoroacetate and sulfur

Feng, Wei,Zhang, Xing-Guo

, p. 1144 - 1147 (2019)

A copper-catalyzed isothiocyanation of amines with sodium bromodifluoroacetate and sulfur in the absence of organophosphine has been established. This approach represents a simple and efficient one-pot synthesis of isothiocyanates, and features excellent functional group tolerance and the use of a cheap, safe and odorless sulfur source. Moreover, this process could directly provide isothiocyanate analogous bioactive molecules, thiocarbonyl-containing pesticides and facile construction of benzoxazole and benzimidazole frames.
