Check Digit Verification of cas no

The CAS Registry Mumber 7137-88-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,1,3 and 7 respectively; the second part has 2 digits, 8 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 7137-88:
(6*7)+(5*1)+(4*3)+(3*7)+(2*8)+(1*8)=104
104 % 10 = 4
So 7137-88-4 is a valid CAS Registry Number.
