Check Digit Verification of cas no

The CAS Registry Mumber 55480-59-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,5,4,8 and 0 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 55480-59:
(7*5)+(6*5)+(5*4)+(4*8)+(3*0)+(2*5)+(1*9)=136
136 % 10 = 6
So 55480-59-6 is a valid CAS Registry Number.

A convenient general synthesis of 3-substituted 2H-chromene derivatives

Kaye, Perry T.,Nocanda, Xolani W.

, p. 1318 - 1323 (2002)

Reactions of 2-hydroxybenzaldehydes and 2-hydroxy-1-naphthaldehydes with various activated alkenes under Baylis-Hillman conditions have been shown to proceed with regioselective cyclisation to afford the corresponding 3-substituted chromene derivatives. In some cases competitive dimerisation of the alkene component was observed, and direct dimerisation in the absence of the aldehyde has been explored.
