88017-72-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 88017-72-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,8,0,1 and 7 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 88017-72:
(7*8)+(6*8)+(5*0)+(4*1)+(3*7)+(2*7)+(1*2)=145
145 % 10 = 5
So 88017-72-5 is a valid CAS Registry Number.
