80144-02-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 80144-02-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,0,1,4 and 4 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 80144-02:
(7*8)+(6*0)+(5*1)+(4*4)+(3*4)+(2*0)+(1*2)=91
91 % 10 = 1
So 80144-02-1 is a valid CAS Registry Number.
