850194-84-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 850194-84-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,5,0,1,9 and 4 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 850194-84:
(8*8)+(7*5)+(6*0)+(5*1)+(4*9)+(3*4)+(2*8)+(1*4)=172
172 % 10 = 2
So 850194-84-2 is a valid CAS Registry Number.
