Check Digit Verification of cas no

The CAS Registry Mumber 1399296-23-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,9,9,2,9 and 6 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1399296-23:
(9*1)+(8*3)+(7*9)+(6*9)+(5*2)+(4*9)+(3*6)+(2*2)+(1*3)=221
221 % 10 = 1
So 1399296-23-1 is a valid CAS Registry Number.

Construction of tricyclic pyran derivatives through intramolecular [2+2+2] cycloaddition of allenynes with tethered aldehydes

Oonishi, Yoshihiro,Kitano, Yoshitaka,Sato, Yoshihiro

, p. 7713 - 7718 (2013)

Rh(I)-catalyzed intramolecular [2+2+2] cycloaddition of allenynes with tethered aldehydes was investigated. The cyclizations proceeded smoothly under mild conditions to give various tricyclic compounds containing a pyran ring in good to high yields in a stereoselective manner.
