Check Digit Verification of cas no

The CAS Registry Mumber 681121-99-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,8,1,1,2 and 1 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 681121-99:
(8*6)+(7*8)+(6*1)+(5*1)+(4*2)+(3*1)+(2*9)+(1*9)=153
153 % 10 = 3
So 681121-99-3 is a valid CAS Registry Number.

Phase-transfer-catalyzed asymmetric Darzens reaction using a new chiral ammonium salt

Arai, Shigeru,Tokumaru, Kazuyuki,Aoyama, Toyohiko

, p. 1845 - 1848 (2004)

Catalytic asymmetric Darzens reaction of haloamides is described. A new and easily-prepared bis-ammonium salt derived from BINOL acts as an effective phase-transfer catalyst and efficiently promotes the reaction to give the desired epoxides under quite mild conditions with up to 70% ee.
