Check Digit Verification of cas no

The CAS Registry Mumber 905930-27-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,0,5,9,3 and 0 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 905930-27:
(8*9)+(7*0)+(6*5)+(5*9)+(4*3)+(3*0)+(2*2)+(1*7)=170
170 % 10 = 0
So 905930-27-0 is a valid CAS Registry Number.
