128291-95-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 128291-95-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,2,9 and 1 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 128291-95:
(8*1)+(7*2)+(6*8)+(5*2)+(4*9)+(3*1)+(2*9)+(1*5)=142
142 % 10 = 2
So 128291-95-2 is a valid CAS Registry Number.
