Check Digit Verification of cas no
The CAS Registry Mumber 21100-82-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,1,0 and 0 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 21100-82:
(7*2)+(6*1)+(5*1)+(4*0)+(3*0)+(2*8)+(1*2)=43
43 % 10 = 3
So 21100-82-3 is a valid CAS Registry Number.
