128885-39-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 128885-39-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,8,8 and 5 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 128885-39:
(8*1)+(7*2)+(6*8)+(5*8)+(4*8)+(3*5)+(2*3)+(1*9)=172
172 % 10 = 2
So 128885-39-2 is a valid CAS Registry Number.
