Check Digit Verification of cas no
The CAS Registry Mumber 21380-80-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,3,8 and 0 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 21380-80:
(7*2)+(6*1)+(5*3)+(4*8)+(3*0)+(2*8)+(1*0)=83
83 % 10 = 3
So 21380-80-3 is a valid CAS Registry Number.
