75501-68-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 75501-68-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,5,5,0 and 1 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 75501-68:
(7*7)+(6*5)+(5*5)+(4*0)+(3*1)+(2*6)+(1*8)=127
127 % 10 = 7
So 75501-68-7 is a valid CAS Registry Number.
