Check Digit Verification of cas no
The CAS Registry Mumber 220229-03-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,0,2,2 and 9 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 220229-03:
(8*2)+(7*2)+(6*0)+(5*2)+(4*2)+(3*9)+(2*0)+(1*3)=78
78 % 10 = 8
So 220229-03-8 is a valid CAS Registry Number.
