Check Digit Verification of cas no
The CAS Registry Mumber 221393-18-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,1,3,9 and 3 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 221393-18:
(8*2)+(7*2)+(6*1)+(5*3)+(4*9)+(3*3)+(2*1)+(1*8)=106
106 % 10 = 6
So 221393-18-6 is a valid CAS Registry Number.
