Check Digit Verification of cas no
The CAS Registry Mumber 183074-45-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,3,0,7 and 4 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 183074-45:
(8*1)+(7*8)+(6*3)+(5*0)+(4*7)+(3*4)+(2*4)+(1*5)=135
135 % 10 = 5
So 183074-45-5 is a valid CAS Registry Number.

Asymmetric synthesis of α-hydroxy acids via β-lactams
Srirajan,Deshmukh,Puranik,Bhawal
, p. 2733 - 2738 (1996)
A diastereoselective synthesis of β-lactams 5a-e and 6a-e has been achieved, via a Staudinger reaction using imines derived from (1S)-(+)-camphor-10-sulfonamide, in good yields. The major diastereomers 6a-e were isolated in pure form by crystallization. T
