75235-87-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 75235-87-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,5,2,3 and 5 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 75235-87:
(7*7)+(6*5)+(5*2)+(4*3)+(3*5)+(2*8)+(1*7)=139
139 % 10 = 9
So 75235-87-9 is a valid CAS Registry Number.
