Check Digit Verification of cas no

The CAS Registry Mumber 138328-82-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,3,2 and 8 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 138328-82:
(8*1)+(7*3)+(6*8)+(5*3)+(4*2)+(3*8)+(2*8)+(1*2)=142
142 % 10 = 2
So 138328-82-2 is a valid CAS Registry Number.

Stereoselective reactions. XX. Synthetic studies on optically active β-lactams. III. Stereocontrolled synthesis of chiral intermediate to (+)-thienamycin from D-glucose

Ikota,Yoshino,Koga

, p. 2201 - 2206 (1991)

A chiral key intermediate (19a) for the synthesis of (+)-thienamycin was synthesized starting from D-glucose. The enol ether 13, obtained from the ketone 11 by Horner-Wittig reaction, was transformed to the corresponding methyl ester 16 by pyridinium chlorochromate oxidation or by employing the Wacker process. The ester 16 was further converted to the β-lactam 19a, which is a useful chiral precursor to (+)-thienamycin.
