74588-83-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 74588-83-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,5,8 and 8 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 74588-83:
(7*7)+(6*4)+(5*5)+(4*8)+(3*8)+(2*8)+(1*3)=173
173 % 10 = 3
So 74588-83-3 is a valid CAS Registry Number.
