73685-26-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 73685-26-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,3,6,8 and 5 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 73685-26:
(7*7)+(6*3)+(5*6)+(4*8)+(3*5)+(2*2)+(1*6)=154
154 % 10 = 4
So 73685-26-4 is a valid CAS Registry Number.
