Check Digit Verification of cas no
The CAS Registry Mumber 123265-82-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,3,2,6 and 5 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 123265-82:
(8*1)+(7*2)+(6*3)+(5*2)+(4*6)+(3*5)+(2*8)+(1*2)=107
107 % 10 = 7
So 123265-82-7 is a valid CAS Registry Number.

Asymmetric synthesis of 3-hydroxyprolines by photocyclization of N-(2-benzoylethyl)glycinamides
Wessig,Wettstein,Giese,Neuburger,Zehnder
, p. 829 - 837 (1994)
The chiral N-(2-benzoylethyl)-N-tosylglycinamides 1a-c were prepared from the C2-symmetric pyrrolidines 5a-c. Irradiation of these ketones 1a-c gave cis-3-hydroxyprolinamides 10-12 in moderate to good yields (Scheme 3). The de of the photocycli
