Check Digit Verification of cas no
The CAS Registry Mumber 1622982-49-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,2,2,9,8 and 2 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1622982-49:
(9*1)+(8*6)+(7*2)+(6*2)+(5*9)+(4*8)+(3*2)+(2*4)+(1*9)=183
183 % 10 = 3
So 1622982-49-3 is a valid CAS Registry Number.

Cyclodehydrations leading to indene products having n-heterocyclic substituents
Boblak, Kenneth N.,Klumpp, Douglas A.
, p. 5852 - 5857 (2014/07/08)
In this Note, we describe superacid-promoted cyclodehydrations leading to functionalized indenes. The product indenes are synthesized having N-heterocyclic substituents, including pyridyl, imidazolyl, pyrimdyl, and other groups. A mechanism is proposed in
