42897-32-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 42897-32-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,2,8,9 and 7 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 42897-32:
(7*4)+(6*2)+(5*8)+(4*9)+(3*7)+(2*3)+(1*2)=145
145 % 10 = 5
So 42897-32-5 is a valid CAS Registry Number.
