Check Digit Verification of cas no

The CAS Registry Mumber 127220-32-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,7,2,2 and 0 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 127220-32:
(8*1)+(7*2)+(6*7)+(5*2)+(4*2)+(3*0)+(2*3)+(1*2)=90
90 % 10 = 0
So 127220-32-0 is a valid CAS Registry Number.

Reactions of Trialkylsilyl Trifluoromethanesulfonates XI. - Synthesis of α-Oxocarboxylic Acid Derivatives from 2-O-Functionalized Trimethylsilyl Ketene Acetals

Simchen, Gerhard,Siegl, Gerald

, p. 607 - 614 (2007/10/02)

The cyclic ketene acetals 3, 5 are prepared from the dioxolanone 2 resp. the oxazolidinediones 4 by silylation with trimethylsilyl triflate (1)/triethylamine.In an aldol addition/Peterson olefination reaction catalysed by 1 the ketene acetals 3, 5 yield the (E/Z)-benzylidene derivatives 7, 12, 13 in reaction with aromatic aldehydes 6.In a side reaction the α-(trimethylsilyl)benzylidene derivatives 8 are formed from 3 and 6.Compounds 7 can be hydrolysed to yield α-ketocarboxylic acids 14.The latter are also obtained via β-elimination of trimethylsilanol from 2,3-bis(trimethylsiloxy)carboxylic acid anhydride/DMAP/pyridine. Key Words: 1,3-Dioxolanes / 1,3-Oxazolidines / α-Oxocarboxylic acids
