19493-09-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 19493-09-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,9,4,9 and 3 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 19493-09:
(7*1)+(6*9)+(5*4)+(4*9)+(3*3)+(2*0)+(1*9)=135
135 % 10 = 5
So 19493-09-5 is a valid CAS Registry Number.
