Check Digit Verification of cas no

The CAS Registry Mumber 89991-25-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,9,9,9 and 1 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 89991-25:
(7*8)+(6*9)+(5*9)+(4*9)+(3*1)+(2*2)+(1*5)=203
203 % 10 = 3
So 89991-25-3 is a valid CAS Registry Number.

EXTRUSION REACTIONS-VII. FORMATION OF 2,5-DIARYL-1,4-DITHIINS AND 2-ACETONYL THIAZOLES

Singh, Harjit,Aggarwal, Sunil K.,Malhotra, Nageshwar

, p. 4941 - 4946 (2007/10/02)

ω-(2,6-Dimethyl-4-pyrimidinylthio-(4), 2-methyl-4-quinazolinylthio-(9), and 4-oxo-2-quinazolinylthio)-(10) acetophenones with hydrochloric or perchloric acid provide 2,5-diaryl-1,4-dithiins (7) whereas ω-(6-methyl-4-pyrimidinylthio)acetophenones (11) with aq HCl/HClO4 or POCl3 followed by hydrolysis provide 1-(4-aryl-2-thiazolyl)-2-propanones (12).Likewise, 2-(6-methyl-4-pyrimidinylthio)cyclohexanone (13) give the thiazole derivative (14).
