Check Digit Verification of cas no

The CAS Registry Mumber 56046-67-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,6,0,4 and 6 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 56046-67:
(7*5)+(6*6)+(5*0)+(4*4)+(3*6)+(2*6)+(1*7)=124
124 % 10 = 4
So 56046-67-4 is a valid CAS Registry Number.
