13668-47-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 13668-47-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,6,6 and 8 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 13668-47:
(7*1)+(6*3)+(5*6)+(4*6)+(3*8)+(2*4)+(1*7)=118
118 % 10 = 8
So 13668-47-8 is a valid CAS Registry Number.
