Check Digit Verification of cas no

The CAS Registry Mumber 5719-25-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,7,1 and 9 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 5719-25:
(6*5)+(5*7)+(4*1)+(3*9)+(2*2)+(1*5)=105
105 % 10 = 5
So 5719-25-5 is a valid CAS Registry Number.
