620949-46-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 620949-46-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,2,0,9,4 and 9 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 620949-46:
(8*6)+(7*2)+(6*0)+(5*9)+(4*4)+(3*9)+(2*4)+(1*6)=164
164 % 10 = 4
So 620949-46-4 is a valid CAS Registry Number.
