Check Digit Verification of cas no

The CAS Registry Mumber 2148-09-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,1,4 and 8 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 2148-09:
(6*2)+(5*1)+(4*4)+(3*8)+(2*0)+(1*9)=66
66 % 10 = 6
So 2148-09-6 is a valid CAS Registry Number.
