Check Digit Verification of cas no
The CAS Registry Mumber 66490-20-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,6,4,9 and 0 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 66490-20:
(7*6)+(6*6)+(5*4)+(4*9)+(3*0)+(2*2)+(1*0)=138
138 % 10 = 8
So 66490-20-8 is a valid CAS Registry Number.
