Check Digit Verification of cas no
The CAS Registry Mumber 28667-51-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,8,6,6 and 7 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 28667-51:
(7*2)+(6*8)+(5*6)+(4*6)+(3*7)+(2*5)+(1*1)=148
148 % 10 = 8
So 28667-51-8 is a valid CAS Registry Number.
