Check Digit Verification of cas no
The CAS Registry Mumber 205524-46-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,5,5,2 and 4 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 205524-46:
(8*2)+(7*0)+(6*5)+(5*5)+(4*2)+(3*4)+(2*4)+(1*6)=105
105 % 10 = 5
So 205524-46-5 is a valid CAS Registry Number.
