Check Digit Verification of cas no

The CAS Registry Mumber 4438-94-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,4,3 and 8 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 4438-94:
(6*4)+(5*4)+(4*3)+(3*8)+(2*9)+(1*4)=102
102 % 10 = 2
So 4438-94-2 is a valid CAS Registry Number.
