Check Digit Verification of cas no
The CAS Registry Mumber 221263-97-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,1,2,6 and 3 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 221263-97:
(8*2)+(7*2)+(6*1)+(5*2)+(4*6)+(3*3)+(2*9)+(1*7)=104
104 % 10 = 4
So 221263-97-4 is a valid CAS Registry Number.
