Check Digit Verification of cas no
The CAS Registry Mumber 81256-20-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,2,5 and 6 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 81256-20:
(7*8)+(6*1)+(5*2)+(4*5)+(3*6)+(2*2)+(1*0)=114
114 % 10 = 4
So 81256-20-4 is a valid CAS Registry Number.
