805319-19-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 805319-19-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,0,5,3,1 and 9 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 805319-19:
(8*8)+(7*0)+(6*5)+(5*3)+(4*1)+(3*9)+(2*1)+(1*9)=151
151 % 10 = 1
So 805319-19-1 is a valid CAS Registry Number.
