Check Digit Verification of cas no
The CAS Registry Mumber 127997-06-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,7,9,9 and 7 respectively; the second part has 2 digits, 0 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 127997-06:
(8*1)+(7*2)+(6*7)+(5*9)+(4*9)+(3*7)+(2*0)+(1*6)=172
172 % 10 = 2
So 127997-06-2 is a valid CAS Registry Number.

THE FOUR-CARBON ELONGATION OF THREE-CARBON CHIRAL SYNTHONS USING 2-(TRIMETHYLSILOXY)FURAN: HIGHLY STEREOCONTROLLED ENTRY TO ENANTIOMERICALLY PURE SEVEN-CARBON α,β-UNSATURATED 2,3-DIDEOXYALDONOLACTONES

The BF3-promoted addition of 2-(trimethylsiloxy)furan to three carbon synthons derived from D- and L-glyceraldehyde, D- and L-serinal, and imines thereof furnishes C7 α,β-unsaturated 2,3-dideoxy-aldonolactone derivatives in high yield, with very high level of diastereoselection.In all the cases, compounds having 4,5-threo:5,6-erythro relative stereodisposition preferentially emerge from the reactions, accompanied by only marginal amounts of 4,5-erythro:5,6-threo epimers.An empirical rule for the rapid assignment of the configuration at C-4 (γ-carbon) of γ-substituted unsaturated and saturated β-butyrolactones is given, based upon the sign of the optical rotation values.
