65939-18-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 65939-18-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,5,9,3 and 9 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 65939-18:
(7*6)+(6*5)+(5*9)+(4*3)+(3*9)+(2*1)+(1*8)=166
166 % 10 = 6
So 65939-18-6 is a valid CAS Registry Number.
