Check Digit Verification of cas no
The CAS Registry Mumber 128555-16-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,5,5 and 5 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 128555-16:
(8*1)+(7*2)+(6*8)+(5*5)+(4*5)+(3*5)+(2*1)+(1*6)=138
138 % 10 = 8
So 128555-16-8 is a valid CAS Registry Number.
