Check Digit Verification of cas no

The CAS Registry Mumber 1256-49-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,2,5 and 6 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1256-49:
(6*1)+(5*2)+(4*5)+(3*6)+(2*4)+(1*9)=71
71 % 10 = 1
So 1256-49-1 is a valid CAS Registry Number.
