Check Digit Verification of cas no

The CAS Registry Mumber 1338726-07-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,3,8,7,2 and 6 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1338726-07:
(9*1)+(8*3)+(7*3)+(6*8)+(5*7)+(4*2)+(3*6)+(2*0)+(1*7)=170
170 % 10 = 0
So 1338726-07-0 is a valid CAS Registry Number.
