Check Digit Verification of cas no

The CAS Registry Mumber 1141498-04-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,4,1,4,9 and 8 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1141498-04:
(9*1)+(8*1)+(7*4)+(6*1)+(5*4)+(4*9)+(3*8)+(2*0)+(1*4)=135
135 % 10 = 5
So 1141498-04-5 is a valid CAS Registry Number.

Synthesis of trans-2-Substituted Cyclopropylamines from α-Chloroaldehydes

West, Michael S.,Mills, L. Reginald,McDonald, Tyler R.,Lee, Jessica B.,Ensan, Deeba,Rousseaux, Sophie A. L.

, p. 8409 - 8413 (2019)

Cyclopropylamines are prevalent in pharmaceuticals and agrochemicals. Herein, we report the synthesis of trans-2-substituted cyclopropylamines in high diastereoselectivity from readily available α-chloroaldehydes. The reaction proceeds via trapping of an electrophilic zinc homoenolate with an amine followed by ring closure to generate the cyclopropylamine. We have also observed that cyclopropylamine cis/trans-isomerization occurs in the presence of zinc halide salts and that this process can be turned off by the addition of a polar aprotic cosolvent.
