Check Digit Verification of cas no

The CAS Registry Mumber 23138-69-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,3,1,3 and 8 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 23138-69:
(7*2)+(6*3)+(5*1)+(4*3)+(3*8)+(2*6)+(1*9)=94
94 % 10 = 4
So 23138-69-4 is a valid CAS Registry Number.
