5698-42-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 5698-42-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,6,9 and 8 respectively; the second part has 2 digits, 4 and 2 respectively.Calculate Digit Verification of CAS Registry Number 5698-42:
(6*5)+(5*6)+(4*9)+(3*8)+(2*4)+(1*2)=130
130 % 10 = 0
So 5698-42-0 is a valid CAS Registry Number.
