74041-01-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 74041-01-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,0,4 and 1 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 74041-01:
(7*7)+(6*4)+(5*0)+(4*4)+(3*1)+(2*0)+(1*1)=93
93 % 10 = 3
So 74041-01-3 is a valid CAS Registry Number.
