258849-83-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 258849-83-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,5,8,8,4 and 9 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 258849-83:
(8*2)+(7*5)+(6*8)+(5*8)+(4*4)+(3*9)+(2*8)+(1*3)=201
201 % 10 = 1
So 258849-83-1 is a valid CAS Registry Number.

Synthesis of 1,4-benzodiazepine-1-carbothioamides, bicyclic analogues of the TIBO-type anti-HIV agents
Liu,Dodd
, p. 523 - 528 (2007/10/02)
A series of N'-substituted 1,4-benzodiazepine-1-carbothioamides 2a-j were prepared by reacting the precursor 1,4-benzodiazepine 11 with the corresponding N-substituted isothiocyanates 2a-i or with sodium thiocyanate-trifluoroacetic acid (2j). Despite the
