36993-99-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 36993-99-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,6,9,9 and 3 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 36993-99:
(7*3)+(6*6)+(5*9)+(4*9)+(3*3)+(2*9)+(1*9)=174
174 % 10 = 4
So 36993-99-4 is a valid CAS Registry Number.

Heterocyclic Variants of the Purine System. II Derivatives of Thiazolo-1,2,4-triazines, a new Heterocyclic Ring System
Jacobsen, Noel W.,Philippides, Athena E.
, p. 693 - 699 (2007/10/02)
Some representative derivatives of the new thiazolo-1,2,4-triazine ring system were prepared from 5-acylamino-1,2,4-triazin-6(1H)-ones by heating with phosphorus pentasulfide in pyridine.Further derivatives of the biheterocyclo system were also mad
