80947-23-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 80947-23-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,0,9,4 and 7 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 80947-23:
(7*8)+(6*0)+(5*9)+(4*4)+(3*7)+(2*2)+(1*3)=145
145 % 10 = 5
So 80947-23-5 is a valid CAS Registry Number.

Herstellung Kondensierter 2-Alkylthio-4-hydroxypyrimidine
Haede, Werner
, p. 1417 - 1419 (2007/10/02)
Aromatic amines and alkoxycarbonyl isothiokyanate give thioureas 7.These are alkylated to S-alkylisothioureas 8, which upon heating lose alcohol to give 2-alkylthio-4-hydroxypyrimidines.
