Check Digit Verification of cas no
The CAS Registry Mumber 949-03-1 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 9,4 and 9 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 949-03:
(5*9)+(4*4)+(3*9)+(2*0)+(1*3)=91
91 % 10 = 1
So 949-03-1 is a valid CAS Registry Number.
