Check Digit Verification of cas no
The CAS Registry Mumber 155144-45-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,5,1,4 and 4 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 155144-45:
(8*1)+(7*5)+(6*5)+(5*1)+(4*4)+(3*4)+(2*4)+(1*5)=119
119 % 10 = 9
So 155144-45-9 is a valid CAS Registry Number.
