182949-50-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 182949-50-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,2,9,4 and 9 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 182949-50:
(8*1)+(7*8)+(6*2)+(5*9)+(4*4)+(3*9)+(2*5)+(1*0)=174
174 % 10 = 4
So 182949-50-4 is a valid CAS Registry Number.

Synthesis of (1R)-(+)-nopinone- and (1S)-(-)-verbenone-derived chiral annulated indenes via electrocyclic reactions
Liu, Chao,Sowa Jr., John R.
, p. 7241 - 7244 (2007/10/03)
Two new chiral annulated indene derivatives have been stereoselectively synthesized via acid-catalyzed electrocyclic reactions from naturally occurring homochiral precursors (1R)-(+)-nopinone and (1S)-(-)-verbenone.
