218621-39-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 218621-39-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,8,6,2 and 1 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 218621-39:
(8*2)+(7*1)+(6*8)+(5*6)+(4*2)+(3*1)+(2*3)+(1*9)=127
127 % 10 = 7
So 218621-39-7 is a valid CAS Registry Number.
