Check Digit Verification of cas no
The CAS Registry Mumber 221220-99-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,1,2,2 and 0 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 221220-99:
(8*2)+(7*2)+(6*1)+(5*2)+(4*2)+(3*0)+(2*9)+(1*9)=81
81 % 10 = 1
So 221220-99-1 is a valid CAS Registry Number.
