Check Digit Verification of cas no
The CAS Registry Mumber 2653-66-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,6,5 and 3 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 2653-66:
(6*2)+(5*6)+(4*5)+(3*3)+(2*6)+(1*6)=89
89 % 10 = 9
So 2653-66-9 is a valid CAS Registry Number.
