Check Digit Verification of cas no

The CAS Registry Mumber 1047987-39-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,4,7,9,8 and 7 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1047987-39:
(9*1)+(8*0)+(7*4)+(6*7)+(5*9)+(4*8)+(3*7)+(2*3)+(1*9)=192
192 % 10 = 2
So 1047987-39-2 is a valid CAS Registry Number.

Rearrangement of 2-hydroxyalkylazetidines into 3-fluoropyrrolidines

Drouillat, Bruno,Couty, Fran?ois,David, Olivier,Evano, Gwilherm,Marrot, Jérome

scheme or table, p. 1345 - 1348 (2009/04/06)

Upon treatment with DAST (diethylaminosulfur trifluoride) enantiopure 2-hydroxyalkylazetidines rearrange into 3-fluoropyrrolidines. The reaction is stereospecific and involves a bicyclic 1-azoniabicyclo[2.1.0]pentane intermediate which is regioselectively opened by a fluoride anion. Georg Thieme Verlag Stuttgart.
