41249-66-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 41249-66-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,1,2,4 and 9 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 41249-66:
(7*4)+(6*1)+(5*2)+(4*4)+(3*9)+(2*6)+(1*6)=105
105 % 10 = 5
So 41249-66-5 is a valid CAS Registry Number.
