Check Digit Verification of cas no
The CAS Registry Mumber 220999-88-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,0,9,9 and 9 respectively; the second part has 2 digits, 8 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 220999-88:
(8*2)+(7*2)+(6*0)+(5*9)+(4*9)+(3*9)+(2*8)+(1*8)=162
162 % 10 = 2
So 220999-88-2 is a valid CAS Registry Number.
