Check Digit Verification of cas no
The CAS Registry Mumber 66839-66-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,6,8,3 and 9 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 66839-66:
(7*6)+(6*6)+(5*8)+(4*3)+(3*9)+(2*6)+(1*6)=175
175 % 10 = 5
So 66839-66-5 is a valid CAS Registry Number.
