81665-02-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 81665-02-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,6,6 and 5 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 81665-02:
(7*8)+(6*1)+(5*6)+(4*6)+(3*5)+(2*0)+(1*2)=133
133 % 10 = 3
So 81665-02-3 is a valid CAS Registry Number.
