Check Digit Verification of cas no
The CAS Registry Mumber 90253-22-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,2,5 and 3 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 90253-22:
(7*9)+(6*0)+(5*2)+(4*5)+(3*3)+(2*2)+(1*2)=108
108 % 10 = 8
So 90253-22-8 is a valid CAS Registry Number.

Syntheses with Aliphatic Dialdehydes, XXXVIII. - Synthesis and Properties of Cycloalkylmalonaldehydes
Reichardt, Christian,Ferwanah, Abdel-Rahman,Pressler, Wilfried,Yun, Kyeong-Yeol
, p. 649 - 679 (2007/10/02)
Vilsmeier formylation of cycloalkyl-substituted enol ethers (7,14a - c,23) yields the cycloalkylmalonaldehydes 1 - 5 for the first time.In solution 1 - 5 exist in the (E)-s-(E) enol form as vinylogous carboxylic acids.The reaction of 1 - 5 with suitable electrophiles and nucleophiles leads to cycloalkyl-substituted open-chain (29,30), carbocyclic (31) as well as heterocyclic compounds (32-40) with peculiar properties due to the presence of the lipophilic cycloalkyl group.
