Check Digit Verification of cas no
The CAS Registry Mumber 54851-36-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,4,8,5 and 1 respectively; the second part has 2 digits, 3 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 54851-36:
(7*5)+(6*4)+(5*8)+(4*5)+(3*1)+(2*3)+(1*6)=134
134 % 10 = 4
So 54851-36-4 is a valid CAS Registry Number.

Reaction of 4-Chloropyrimidines with Alkylisothioureas
Hurst, Derek T.
, p. 697 - 700 (2007/10/02)
4,6-Dichloro-5-nitropyrimidine reacts with S-methylisothiouronium sulfate to give 1-(4-chloro-5-nitropyrimidin-6-yl)-S-methylisothiourea by an unusual nucleophilic attack involving an isothiouronium nitrogen atom.
