Check Digit Verification of cas no
The CAS Registry Mumber 11103-91-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,1,1,0 and 3 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 11103-91:
(7*1)+(6*1)+(5*1)+(4*0)+(3*3)+(2*9)+(1*1)=46
46 % 10 = 6
So 11103-91-6 is a valid CAS Registry Number.
