123445-48-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 123445-48-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,3,4,4 and 5 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 123445-48:
(8*1)+(7*2)+(6*3)+(5*4)+(4*4)+(3*5)+(2*4)+(1*8)=107
107 % 10 = 7
So 123445-48-7 is a valid CAS Registry Number.

ASYMMETRIC DIELS-ALDER REACTIONS OF CHIRAL ALKOXY IMINIUM SALTS
Jung, Michael E.,Vaccaro, Wayne D.,Buszek, Keith R.
, p. 1893 - 1896 (2007/10/02)
The optically active vinyl trimethylsilyloxy iminium salts, prepared from 8 and 14ab, were reacted with cyclopentadiene to give the optically active amides 15 and 16ab in high yield and with good diastereoselectivity.
