128709-95-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 128709-95-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,7,0 and 9 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 128709-95:
(8*1)+(7*2)+(6*8)+(5*7)+(4*0)+(3*9)+(2*9)+(1*5)=155
155 % 10 = 5
So 128709-95-5 is a valid CAS Registry Number.
