87422-53-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 87422-53-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,7,4,2 and 2 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 87422-53:
(7*8)+(6*7)+(5*4)+(4*2)+(3*2)+(2*5)+(1*3)=145
145 % 10 = 5
So 87422-53-5 is a valid CAS Registry Number.
