Check Digit Verification of cas no
The CAS Registry Mumber 303014-07-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,0,3,0,1 and 4 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 303014-07:
(8*3)+(7*0)+(6*3)+(5*0)+(4*1)+(3*4)+(2*0)+(1*7)=65
65 % 10 = 5
So 303014-07-5 is a valid CAS Registry Number.
