89703-66-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 89703-66-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,9,7,0 and 3 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 89703-66:
(7*8)+(6*9)+(5*7)+(4*0)+(3*3)+(2*6)+(1*6)=172
172 % 10 = 2
So 89703-66-2 is a valid CAS Registry Number.
