42470-01-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 42470-01-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,2,4,7 and 0 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 42470-01:
(7*4)+(6*2)+(5*4)+(4*7)+(3*0)+(2*0)+(1*1)=89
89 % 10 = 9
So 42470-01-9 is a valid CAS Registry Number.
