177-52-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 177-52-6 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 1,7 and 7 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 177-52:
(5*1)+(4*7)+(3*7)+(2*5)+(1*2)=66
66 % 10 = 6
So 177-52-6 is a valid CAS Registry Number.
