77197-68-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 77197-68-3 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 7 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 77197-68:
(7*7)+(6*7)+(5*1)+(4*9)+(3*7)+(2*6)+(1*8)=173
173 % 10 = 3
So 77197-68-3 is a valid CAS Registry Number.
