Check Digit Verification of cas no
The CAS Registry Mumber 450336-11-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,5,0,3,3 and 6 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 450336-11:
(8*4)+(7*5)+(6*0)+(5*3)+(4*3)+(3*6)+(2*1)+(1*1)=115
115 % 10 = 5
So 450336-11-5 is a valid CAS Registry Number.
