Check Digit Verification of cas no
The CAS Registry Mumber 81056-61-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,0,5 and 6 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 81056-61:
(7*8)+(6*1)+(5*0)+(4*5)+(3*6)+(2*6)+(1*1)=113
113 % 10 = 3
So 81056-61-3 is a valid CAS Registry Number.
