85068-23-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 85068-23-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,5,0,6 and 8 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 85068-23:
(7*8)+(6*5)+(5*0)+(4*6)+(3*8)+(2*2)+(1*3)=141
141 % 10 = 1
So 85068-23-1 is a valid CAS Registry Number.
