134224-75-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 134224-75-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,4,2,2 and 4 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 134224-75:
(8*1)+(7*3)+(6*4)+(5*2)+(4*2)+(3*4)+(2*7)+(1*5)=102
102 % 10 = 2
So 134224-75-2 is a valid CAS Registry Number.

Syntheses and Reactions of Thiadiazolopyrimidinone Derivatives
Tsuji, Tadakazu
, p. 489 - 492 (2007/10/02)
5-Imino-6H-7-one, 7-amino-5-one and 5-isocyano-7-one derivatives of thiadiazolo- and -thiazolopyrimidines were synthesized. 5-Isocyano-7-one derivatives were obtained by the reaction of the corresponding 5-imino-6H-7-ones with the Vilsm
