Check Digit Verification of cas no
The CAS Registry Mumber 20882-69-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,8,8 and 2 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 20882-69:
(7*2)+(6*0)+(5*8)+(4*8)+(3*2)+(2*6)+(1*9)=113
113 % 10 = 3
So 20882-69-3 is a valid CAS Registry Number.
