Check Digit Verification of cas no

The CAS Registry Mumber 1027940-16-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,2,7,9,4 and 0 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1027940-16:
(9*1)+(8*0)+(7*2)+(6*7)+(5*9)+(4*4)+(3*0)+(2*1)+(1*6)=134
134 % 10 = 4
So 1027940-16-4 is a valid CAS Registry Number.
