41654-24-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 41654-24-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,1,6,5 and 4 respectively; the second part has 2 digits, 2 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 41654-24:
(7*4)+(6*1)+(5*6)+(4*5)+(3*4)+(2*2)+(1*4)=104
104 % 10 = 4
So 41654-24-4 is a valid CAS Registry Number.
