442574-07-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 442574-07-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,4,2,5,7 and 4 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 442574-07:
(8*4)+(7*4)+(6*2)+(5*5)+(4*7)+(3*4)+(2*0)+(1*7)=144
144 % 10 = 4
So 442574-07-4 is a valid CAS Registry Number.
