75587-02-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 75587-02-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,5,5,8 and 7 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 75587-02:
(7*7)+(6*5)+(5*5)+(4*8)+(3*7)+(2*0)+(1*2)=159
159 % 10 = 9
So 75587-02-9 is a valid CAS Registry Number.
