Check Digit Verification of cas no

The CAS Registry Mumber 219864-35-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,9,8,6 and 4 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 219864-35:
(8*2)+(7*1)+(6*9)+(5*8)+(4*6)+(3*4)+(2*3)+(1*5)=164
164 % 10 = 4
So 219864-35-4 is a valid CAS Registry Number.

Triethyl phosphite mediated synthesis of indazoloquinazolinoperimidines, oxadiazoloindazoles and thiadiazoloindazoles

Reddy, V Rama Kishan,Reddy, P S N,Ratnam, C V

, p. 499 - 502 (2007/10/02)

2-(2-Aminophenyl)perimidine (1) on treatment with 2-nitrobenzaldehydes (2) in acetic acid gives 5,6-dihydro-6-(2-nitroaryl)quinazolinoperimidines (4) which on permanganate oxidation yield 6-(2-nitroaryl)quinazolinoperimidines (5). 5-on triethylphosphite (TEP) mediated deoxygenative cyclisation afford indazoloquinazolinoperimidines (6).Similarly, 5-aryl-2-(2-nitrophenyl)oxadiazoles (9) and 2-arylamino-5-(2-nitrophenyl)thiadiazoles (14) on treatment with TEP give 2-aryloxadiazoloindazoles (10) and2-(N-ethylarylamino)thiadiazoloindazoles (16) respectively.
