75420-98-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 75420-98-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,5,4,2 and 0 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 75420-98:
(7*7)+(6*5)+(5*4)+(4*2)+(3*0)+(2*9)+(1*8)=133
133 % 10 = 3
So 75420-98-3 is a valid CAS Registry Number.
