80781-02-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 80781-02-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,0,7,8 and 1 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 80781-02:
(7*8)+(6*0)+(5*7)+(4*8)+(3*1)+(2*0)+(1*2)=128
128 % 10 = 8
So 80781-02-8 is a valid CAS Registry Number.
