Check Digit Verification of cas no

The CAS Registry Mumber 1123200-95-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,2,3,2,0 and 0 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1123200-95:
(9*1)+(8*1)+(7*2)+(6*3)+(5*2)+(4*0)+(3*0)+(2*9)+(1*5)=82
82 % 10 = 2
So 1123200-95-2 is a valid CAS Registry Number.

Organocatalytic asymmetric 1,3-dipolar cycloaddition of nitrones to nitroolefins

Du, Wei,Liu, Yan-Kai,Yue, Lei,Chen, Ying-Chun

experimental part, p. 2997 - 3000 (2009/07/03)

The asymmetric 1,3-dipolar cycloaddition of nitrones to nitroolefins was investigated by employing novel thiourea-containing organocatalysts. This transformation exhibited excellent diastereoselectivities (generally >99:1 dr) and moderate to high enantioselectivities (up to 88% ee). A 2,3-diaminopropanol derivative with three contiguous chiral centers was efficiently prepared from one cycloaddition adduct. Georg Thieme Verlag Stuttgart.
