95755-20-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 95755-20-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,5,7,5 and 5 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 95755-20:
(7*9)+(6*5)+(5*7)+(4*5)+(3*5)+(2*2)+(1*0)=167
167 % 10 = 7
So 95755-20-7 is a valid CAS Registry Number.
