1185004-40-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1185004-40-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,8,5,0,0 and 4 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1185004-40:
(9*1)+(8*1)+(7*8)+(6*5)+(5*0)+(4*0)+(3*4)+(2*4)+(1*0)=123
123 % 10 = 3
So 1185004-40-3 is a valid CAS Registry Number.
