86528-50-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 86528-50-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,6,5,2 and 8 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 86528-50:
(7*8)+(6*6)+(5*5)+(4*2)+(3*8)+(2*5)+(1*0)=159
159 % 10 = 9
So 86528-50-9 is a valid CAS Registry Number.
