Check Digit Verification of cas no
The CAS Registry Mumber 91-26-9 includes 5 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 2 digits, 9 and 1 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 91-26:
(4*9)+(3*1)+(2*2)+(1*6)=49
49 % 10 = 9
So 91-26-9 is a valid CAS Registry Number.
