Check Digit Verification of cas no

The CAS Registry Mumber 1254529-09-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,4,5,2 and 9 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1254529-09:
(9*1)+(8*2)+(7*5)+(6*4)+(5*5)+(4*2)+(3*9)+(2*0)+(1*9)=153
153 % 10 = 3
So 1254529-09-3 is a valid CAS Registry Number.

Enantioselective formal alkenylations of imines catalyzed by axially chiral dicarboxylic acid using vinylogous aza-enamines

Hashimoto, Takuya,Kimura, Hidenori,Maruoka, Keiji

, p. 6844 - 6847 (2010)

(Figure Presented) In the zone: The use of vinylogous azaenamaines (hydrazones) as a source of an alkenyl group has been achieved (see scheme). Unmasking of the aza-enamine moiety opens up a novel approach for the preparation of chiral allylic amines bearing an electron-withdrawing alkene moiety functionalized at the electron-deficient β position.
