Check Digit Verification of cas no
The CAS Registry Mumber 10222-61-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,0,2,2 and 2 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 10222-61:
(7*1)+(6*0)+(5*2)+(4*2)+(3*2)+(2*6)+(1*1)=44
44 % 10 = 4
So 10222-61-4 is a valid CAS Registry Number.
