91998-77-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 91998-77-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,1,9,9 and 8 respectively; the second part has 2 digits, 7 and 7 respectively.Calculate Digit Verification of CAS Registry Number 91998-77:
(7*9)+(6*1)+(5*9)+(4*9)+(3*8)+(2*7)+(1*7)=195
195 % 10 = 5
So 91998-77-5 is a valid CAS Registry Number.
