128592-69-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 128592-69-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,5,9 and 2 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 128592-69:
(8*1)+(7*2)+(6*8)+(5*5)+(4*9)+(3*2)+(2*6)+(1*9)=158
158 % 10 = 8
So 128592-69-8 is a valid CAS Registry Number.
