28280-67-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 28280-67-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,8,2,8 and 0 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 28280-67:
(7*2)+(6*8)+(5*2)+(4*8)+(3*0)+(2*6)+(1*7)=123
123 % 10 = 3
So 28280-67-3 is a valid CAS Registry Number.

Synthesis of New Substituted as-Triazine-6-carboxylic Acids and as-Triazine-6-yl-alkanoic Acids
Heinisch, L.
, p. 290 - 300 (2007/10/02)
New substituted 3-amino-, 5-amino- and 3,5-diamino-as-triazine-6-carboxylic acids 4a, b, 5a, b and 6 were obtained by the hydrolysis 6-azalumazine derivatives 3a-e.Corresponding acids of the structure 10a-d, 11a, b and 12 were synthesized from 5-chlor-3-m
