85539-78-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 85539-78-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,5,5,3 and 9 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 85539-78:
(7*8)+(6*5)+(5*5)+(4*3)+(3*9)+(2*7)+(1*8)=172
172 % 10 = 2
So 85539-78-2 is a valid CAS Registry Number.
