Check Digit Verification of cas no

The CAS Registry Mumber 137568-92-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,7,5,6 and 8 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 137568-92:
(8*1)+(7*3)+(6*7)+(5*5)+(4*6)+(3*8)+(2*9)+(1*2)=164
164 % 10 = 4
So 137568-92-4 is a valid CAS Registry Number.
