Check Digit Verification of cas no
The CAS Registry Mumber 123033-16-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,3,0,3 and 3 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 123033-16:
(8*1)+(7*2)+(6*3)+(5*0)+(4*3)+(3*3)+(2*1)+(1*6)=69
69 % 10 = 9
So 123033-16-9 is a valid CAS Registry Number.
