77363-79-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 77363-79-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,3,6 and 3 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 77363-79:
(7*7)+(6*7)+(5*3)+(4*6)+(3*3)+(2*7)+(1*9)=162
162 % 10 = 2
So 77363-79-2 is a valid CAS Registry Number.
