Check Digit Verification of cas no
The CAS Registry Mumber 91409-99-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,1,4,0 and 9 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 91409-99:
(7*9)+(6*1)+(5*4)+(4*0)+(3*9)+(2*9)+(1*9)=143
143 % 10 = 3
So 91409-99-3 is a valid CAS Registry Number.
