128072-66-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 128072-66-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,0,7 and 2 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 128072-66:
(8*1)+(7*2)+(6*8)+(5*0)+(4*7)+(3*2)+(2*6)+(1*6)=122
122 % 10 = 2
So 128072-66-2 is a valid CAS Registry Number.
