42045-85-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 42045-85-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,2,0,4 and 5 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 42045-85:
(7*4)+(6*2)+(5*0)+(4*4)+(3*5)+(2*8)+(1*5)=92
92 % 10 = 2
So 42045-85-2 is a valid CAS Registry Number.
