91777-76-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 91777-76-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,1,7,7 and 7 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 91777-76:
(7*9)+(6*1)+(5*7)+(4*7)+(3*7)+(2*7)+(1*6)=173
173 % 10 = 3
So 91777-76-3 is a valid CAS Registry Number.
