75649-99-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 75649-99-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,5,6,4 and 9 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 75649-99:
(7*7)+(6*5)+(5*6)+(4*4)+(3*9)+(2*9)+(1*9)=179
179 % 10 = 9
So 75649-99-9 is a valid CAS Registry Number.
