Check Digit Verification of cas no
The CAS Registry Mumber 154405-45-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,4,4,0 and 5 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 154405-45:
(8*1)+(7*5)+(6*4)+(5*4)+(4*0)+(3*5)+(2*4)+(1*5)=115
115 % 10 = 5
So 154405-45-5 is a valid CAS Registry Number.
