74046-24-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 74046-24-5 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 6 respectively; the second part has 2 digits, 2 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 74046-24:
(7*7)+(6*4)+(5*0)+(4*4)+(3*6)+(2*2)+(1*4)=115
115 % 10 = 5
So 74046-24-5 is a valid CAS Registry Number.
