77196-26-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 77196-26-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,1,9 and 6 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 77196-26:
(7*7)+(6*7)+(5*1)+(4*9)+(3*6)+(2*2)+(1*6)=160
160 % 10 = 0
So 77196-26-0 is a valid CAS Registry Number.
