74940-41-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 74940-41-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,9,4 and 0 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 74940-41:
(7*7)+(6*4)+(5*9)+(4*4)+(3*0)+(2*4)+(1*1)=143
143 % 10 = 3
So 74940-41-3 is a valid CAS Registry Number.
