34185-28-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 34185-28-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,4,1,8 and 5 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 34185-28:
(7*3)+(6*4)+(5*1)+(4*8)+(3*5)+(2*2)+(1*8)=109
109 % 10 = 9
So 34185-28-9 is a valid CAS Registry Number.
