Check Digit Verification of cas no

The CAS Registry Mumber 138890-07-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,8,9 and 0 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 138890-07:
(8*1)+(7*3)+(6*8)+(5*8)+(4*9)+(3*0)+(2*0)+(1*7)=160
160 % 10 = 0
So 138890-07-0 is a valid CAS Registry Number.

DIELS-ALDER REACTION OF PHOTOENOL OF 2-METHYLBENZALDEHYDE WITH 5-ALKYLIDENE-1,3-DIOXANE-4,6-DIONE DERIVATIVES

Tsuno, Takashi,Sugiyama, Kunio

, p. 1989 - 2004 (2007/10/02)

Spiro- and polyspirocyclic compounds containing the 1,2,3,4-tetrahydro-1-naphthol structure were obtained by the Diels-Alder reaction of the photoenol on 2-methylbenzaldehyde with 5-alkylidene-1,3-dioxane-4,6-dione derivatives.The cycloaddition proceeded regio- and stereoselectively.However, in the case using 5-benzylidene-2,2-dimethyl-1,3-dioxane-4,6-dione and diethyl isobutylidenemalonate, the cycloaddition failed.
