121409-90-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 121409-90-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,1,4,0 and 9 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 121409-90:
(8*1)+(7*2)+(6*1)+(5*4)+(4*0)+(3*9)+(2*9)+(1*0)=93
93 % 10 = 3
So 121409-90-3 is a valid CAS Registry Number.

REACTION OF DIANIONS DERIVED FROM β-KETOESTERS WITH EPOXIDES - UTILITY IN THE PREPARATION OF SYNTHETICALLY USEFUL TETRAHYDROFURANS.

Lygo, Barry,O'connor, Norval,Wilson, Peter R.

, p. 6881 - 6888 (1988)

Presented here are several examples which demonstrate that ether substituents α- or β- to an epoxide ring can be tolerated in the ring-opening reaction with β-keto ester dianions.Subsequent acid-promoted cyclisation of the γ-hydroxy β-ketoesters then leads to synthetically useful tetrahydrofurans, as demonstrated by application of this approach to the preparation of (+/-)-methyl nonactate and (+/-)-methyl 8-epi-nonactate.
