Check Digit Verification of cas no
The CAS Registry Mumber 228121-39-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,8,1,2 and 1 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 228121-39:
(8*2)+(7*2)+(6*8)+(5*1)+(4*2)+(3*1)+(2*3)+(1*9)=109
109 % 10 = 9
So 228121-39-9 is a valid CAS Registry Number.
