Check Digit Verification of cas no

The CAS Registry Mumber 55334-39-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,5,3,3 and 4 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 55334-39:
(7*5)+(6*5)+(5*3)+(4*3)+(3*4)+(2*3)+(1*9)=119
119 % 10 = 9
So 55334-39-9 is a valid CAS Registry Number.

CLAISEN REARRANGEMENTS-XII SYNHESIS OF THE COUMARINS, 5-METHOXYSESELIN, TRACHYPHYLLIN, COUMURRAYIN AND XANTHOXYLETIN

Murray, R. D. H.,Jorge, Z. D.

, p. 3129 - 3132 (1984)

The structure of the natural coumarins, 5-methoxyseselin 7 and trachyphyllin 14 have been confirmed by total syntheses from 7-acetoxy-5-prenyloxycoumarin 1 in good overall yields.Convenient synthetic routes to the natural coumarins, coumurrayin 4 and xanthoxyletin 10 have also been established.
