Check Digit Verification of cas no

The CAS Registry Mumber 203934-92-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,3,9,3 and 4 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 203934-92:
(8*2)+(7*0)+(6*3)+(5*9)+(4*3)+(3*4)+(2*9)+(1*2)=123
123 % 10 = 3
So 203934-92-3 is a valid CAS Registry Number.

The structural requirements for inhibition of proteasome function by the lactacystin-derived β-lactone and synthetic analogs

Corey,Li, Wei-Dong Z.,Nagamitsu, Tohru,Fenteany, Gabriel

, p. 3305 - 3316 (2007/10/03)

The synthesis of analogs of the lactacystin-derived β-lactone (2) in which the substituents at C(5), C(7) and C(9) were systematically varied has led to a well defined structure-activity correlation for the highly selective inhibition of the mammalian 20 S proteasome.

A new magnesium-catalyzed doubly diastereoselective anti-aldol reaction leads to a highly efficient process for the total synthesis of lactacystin in quantity

Corey,Li, Weidong,Reichard, Gregory A.

, p. 2330 - 2336 (2007/10/03)

A new process is described for metal-catalyzed doubly diastereoselective Mukaiyama aldol coupling of a chiral tertiary α-amino aldehyde and an achiral silyl enol ether to form selectively an anti-aldol product. The metal requirement is strict, since of se
