Check Digit Verification of cas no
The CAS Registry Mumber 188818-21-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,8,8,1 and 8 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 188818-21:
(8*1)+(7*8)+(6*8)+(5*8)+(4*1)+(3*8)+(2*2)+(1*1)=185
185 % 10 = 5
So 188818-21-5 is a valid CAS Registry Number.
