51738-11-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 51738-11-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,1,7,3 and 8 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 51738-11:
(7*5)+(6*1)+(5*7)+(4*3)+(3*8)+(2*1)+(1*1)=115
115 % 10 = 5
So 51738-11-5 is a valid CAS Registry Number.
