82235-17-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 82235-17-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,2,2,3 and 5 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 82235-17:
(7*8)+(6*2)+(5*2)+(4*3)+(3*5)+(2*1)+(1*7)=114
114 % 10 = 4
So 82235-17-4 is a valid CAS Registry Number.
