Check Digit Verification of cas no
The CAS Registry Mumber 130422-44-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,0,4,2 and 2 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 130422-44:
(8*1)+(7*3)+(6*0)+(5*4)+(4*2)+(3*2)+(2*4)+(1*4)=75
75 % 10 = 5
So 130422-44-5 is a valid CAS Registry Number.

STEREOSPECIFIC SYNTHESES OF 3-SPIRO-EPOXYAZETIDIN-2-ONES
Sharma, Madan Kumar,Durst, Tony
, p. 3249 - 3252 (2007/10/02)
Isomerically pure 3-benzyloxy-3-hydroxyethylazeditin-2-ones, prepared by non-chelation controlled L-Selectride reduction of 3-acetyl-3-benzyloxyazetidin-2-ones, have been converted into the both possible 3-spiro-epoxyazetidin-2-ones.
