Check Digit Verification of cas no

The CAS Registry Mumber 7551-38-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,5,5 and 1 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 7551-38:
(6*7)+(5*5)+(4*5)+(3*1)+(2*3)+(1*8)=104
104 % 10 = 4
So 7551-38-4 is a valid CAS Registry Number.
