77803-67-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 77803-67-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,8,0 and 3 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 77803-67:
(7*7)+(6*7)+(5*8)+(4*0)+(3*3)+(2*6)+(1*7)=159
159 % 10 = 9
So 77803-67-9 is a valid CAS Registry Number.

, p. 149 - 169 (2007/10/02)
3-Carboxyalkylthio derivatives of 5-alkoxyphenyl-1,2,4-triazole were prepared, performing some substitutions both on carboxyalkyl chain, by lengthening it or introducing substituents with increasing molecular weight in α- at the carboxy group, and on N-4
