Check Digit Verification of cas no

The CAS Registry Mumber 5044-61-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,0,4 and 4 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 5044-61:
(6*5)+(5*0)+(4*4)+(3*4)+(2*6)+(1*1)=71
71 % 10 = 1
So 5044-61-1 is a valid CAS Registry Number.

ORGANOPHOSPHORUS CHEMISTRY, 27. THE REACTION OF ISATIN, 5-METHYLISATIN AND THEIR MONOXIMES WITH ALKYL PHOSPHITES, TRIPHENYLPHOSPHINE AND PHOSPHORUS YLIDES

Mahran, M. R. H.,Khidre, M. D.,Abdou, W. M.

, p. 17 - 28 (2007/10/02)

5-Methylisatin (1b) reacts with TAP (4a-c) and/or DAP (3a-c) to give the respective dialkyl α-hydroxyphosphonates (8a-c).Isatin-monoxime (5a) and 5-methyl isatin-monoxime (5b) react with alkyl phosphites to give dialkyl 2-oxo-indolyl phosphonates (8a-c, 12a-f, 15a-c) as major products.The carbonyl-group at position - 3 in 1b is deoxygenated by triphenylphosphine to give a new phosphorus ylide (17) and by methylenetriphenylphosphoranes (Wittig-reagents, 7a-c) to afford the respective 3-substituted methylenes (19a-c) in good yields.Possible reaction mechanisms were considered and structural assignments were based upon analytical, chemical and spectroscopic (IR, 1H NMR, 31P NMR and MS) results. Key words: Isatins, isatinmonoximes, phosphorylation, triphenylphsophine, Wittig-reaction.
