Check Digit Verification of cas no
The CAS Registry Mumber 205443-29-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,5,4,4 and 3 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 205443-29:
(8*2)+(7*0)+(6*5)+(5*4)+(4*4)+(3*3)+(2*2)+(1*9)=104
104 % 10 = 4
So 205443-29-4 is a valid CAS Registry Number.
