74600-42-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 74600-42-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,6,0 and 0 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 74600-42:
(7*7)+(6*4)+(5*6)+(4*0)+(3*0)+(2*4)+(1*2)=113
113 % 10 = 3
So 74600-42-3 is a valid CAS Registry Number.
