Check Digit Verification of cas no

The CAS Registry Mumber 381729-50-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,8,1,7,2 and 9 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 381729-50:
(8*3)+(7*8)+(6*1)+(5*7)+(4*2)+(3*9)+(2*5)+(1*0)=166
166 % 10 = 6
So 381729-50-6 is a valid CAS Registry Number.
