72695-45-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 72695-45-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,2,6,9 and 5 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 72695-45:
(7*7)+(6*2)+(5*6)+(4*9)+(3*5)+(2*4)+(1*5)=155
155 % 10 = 5
So 72695-45-5 is a valid CAS Registry Number.
