77988-77-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 77988-77-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,9,8 and 8 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 77988-77:
(7*7)+(6*7)+(5*9)+(4*8)+(3*8)+(2*7)+(1*7)=213
213 % 10 = 3
So 77988-77-3 is a valid CAS Registry Number.
