99819-49-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 99819-49-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,9,8,1 and 9 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 99819-49:
(7*9)+(6*9)+(5*8)+(4*1)+(3*9)+(2*4)+(1*9)=205
205 % 10 = 5
So 99819-49-5 is a valid CAS Registry Number.

CONDENSED HETEROCYCLES WITH A THIAZOLE RING. 10. THIAZOLOTRIAZINES
Kovtun, Yu. P.,Romanov, N. N.
, p. 413 - 417 (2007/10/02)
Derivatives of a new heterocyclic system, viz., the thiazolotriazinium ion, were obtained by condensation of cyanobenzyl benzenesulfonate with substituted N-dithiocarboxyhydrazones of 1,2-diketones and α-isonitroso ketones.
