Check Digit Verification of cas no

The CAS Registry Mumber 3940-07-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,9,4 and 0 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 3940-07:
(6*3)+(5*9)+(4*4)+(3*0)+(2*0)+(1*7)=86
86 % 10 = 6
So 3940-07-6 is a valid CAS Registry Number.
