Check Digit Verification of cas no

The CAS Registry Mumber 1221972-24-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,2,1,9,7 and 2 respectively; the second part has 2 digits, 2 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1221972-24:
(9*1)+(8*2)+(7*2)+(6*1)+(5*9)+(4*7)+(3*2)+(2*2)+(1*4)=132
132 % 10 = 2
So 1221972-24-2 is a valid CAS Registry Number.

Iron-Catalyzed Synthesis of α-Dienyl Five- and Six-Membered N-Heterocycles

Gonnard, Laurine,Guérinot, Amandine,Cossy, Janine

supporting information, p. 6160 - 6167 (2017/11/15)

The iron-catalyzed synthesis of α-dienyl N-heterocycles is reported. The method is cost-effective, atom-economic, and led to a range of substituted α-dienyl heterocycles in moderate to good yields and diastereoselectivities. The α-dienyl piperidines are key synthetic intermediates as demonstrated by the preparation of a panel of α-polyenyl N-heterocycles.
