Check Digit Verification of cas no
The CAS Registry Mumber 990-91-0 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 9,9 and 0 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 990-91:
(5*9)+(4*9)+(3*0)+(2*9)+(1*1)=100
100 % 10 = 0
So 990-91-0 is a valid CAS Registry Number.
