58404-74-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 58404-74-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,8,4,0 and 4 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 58404-74:
(7*5)+(6*8)+(5*4)+(4*0)+(3*4)+(2*7)+(1*4)=133
133 % 10 = 3
So 58404-74-3 is a valid CAS Registry Number.
