74568-56-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 74568-56-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,5,6 and 8 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 74568-56:
(7*7)+(6*4)+(5*5)+(4*6)+(3*8)+(2*5)+(1*6)=162
162 % 10 = 2
So 74568-56-2 is a valid CAS Registry Number.
