85761-19-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 85761-19-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,5,7,6 and 1 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 85761-19:
(7*8)+(6*5)+(5*7)+(4*6)+(3*1)+(2*1)+(1*9)=159
159 % 10 = 9
So 85761-19-9 is a valid CAS Registry Number.
