73764-31-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 73764-31-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,3,7,6 and 4 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 73764-31:
(7*7)+(6*3)+(5*7)+(4*6)+(3*4)+(2*3)+(1*1)=145
145 % 10 = 5
So 73764-31-5 is a valid CAS Registry Number.
