Check Digit Verification of cas no

The CAS Registry Mumber 905845-01-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,0,5,8,4 and 5 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 905845-01:
(8*9)+(7*0)+(6*5)+(5*8)+(4*4)+(3*5)+(2*0)+(1*1)=174
174 % 10 = 4
So 905845-01-4 is a valid CAS Registry Number.
