649570-55-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 649570-55-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,4,9,5,7 and 0 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 649570-55:
(8*6)+(7*4)+(6*9)+(5*5)+(4*7)+(3*0)+(2*5)+(1*5)=198
198 % 10 = 8
So 649570-55-8 is a valid CAS Registry Number.
