87242-63-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 87242-63-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,7,2,4 and 2 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 87242-63:
(7*8)+(6*7)+(5*2)+(4*4)+(3*2)+(2*6)+(1*3)=145
145 % 10 = 5
So 87242-63-5 is a valid CAS Registry Number.
