Check Digit Verification of cas no

The CAS Registry Mumber 190964-86-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,0,9,6 and 4 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 190964-86:
(8*1)+(7*9)+(6*0)+(5*9)+(4*6)+(3*4)+(2*8)+(1*6)=174
174 % 10 = 4
So 190964-86-4 is a valid CAS Registry Number.
