128093-32-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 128093-32-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,0,9 and 3 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 128093-32:
(8*1)+(7*2)+(6*8)+(5*0)+(4*9)+(3*3)+(2*3)+(1*2)=123
123 % 10 = 3
So 128093-32-3 is a valid CAS Registry Number.
