1154035-28-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1154035-28-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,5,4,0,3 and 5 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1154035-28:
(9*1)+(8*1)+(7*5)+(6*4)+(5*0)+(4*3)+(3*5)+(2*2)+(1*8)=115
115 % 10 = 5
So 1154035-28-5 is a valid CAS Registry Number.
