Check Digit Verification of cas no
The CAS Registry Mumber 568-21-8 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 5,6 and 8 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 568-21:
(5*5)+(4*6)+(3*8)+(2*2)+(1*1)=78
78 % 10 = 8
So 568-21-8 is a valid CAS Registry Number.
