Check Digit Verification of cas no

The CAS Registry Mumber 1383129-40-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,8,3,1,2 and 9 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1383129-40:
(9*1)+(8*3)+(7*8)+(6*3)+(5*1)+(4*2)+(3*9)+(2*4)+(1*0)=155
155 % 10 = 5
So 1383129-40-5 is a valid CAS Registry Number.

Desymmetrization of cyclohexadienones viad-camphor-derived triazolium salt catalyzed intramolecular Stetter reaction

Jia, Min-Qiang,You, Shu-Li

, p. 6363 - 6365 (2012/08/14)

Enantioselective desymmetrization of cyclohexadienones via a d-camphor-derived triazolium salt catalyzed intramolecular Stetter reaction was realized. With 10 mol% of camphor-derived triazolium salt E and 10 mol% of DIEA, various substituted cyclohexadienones proceeded through an intramolecular Stetter reaction, affording tricyclic products in moderate to good yields and excellent ee.
