269058-53-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 269058-53-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,6,9,0,5 and 8 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 269058-53:
(8*2)+(7*6)+(6*9)+(5*0)+(4*5)+(3*8)+(2*5)+(1*3)=169
169 % 10 = 9
So 269058-53-9 is a valid CAS Registry Number.
