77131-61-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 77131-61-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,1,3 and 1 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 77131-61:
(7*7)+(6*7)+(5*1)+(4*3)+(3*1)+(2*6)+(1*1)=124
124 % 10 = 4
So 77131-61-4 is a valid CAS Registry Number.
