72738-52-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 72738-52-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,2,7,3 and 8 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 72738-52:
(7*7)+(6*2)+(5*7)+(4*3)+(3*8)+(2*5)+(1*2)=144
144 % 10 = 4
So 72738-52-4 is a valid CAS Registry Number.
