Check Digit Verification of cas no
The CAS Registry Mumber 991-07-1 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 1 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 991-07:
(5*9)+(4*9)+(3*1)+(2*0)+(1*7)=91
91 % 10 = 1
So 991-07-1 is a valid CAS Registry Number.
