61031-83-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 61031-83-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,1,0,3 and 1 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 61031-83:
(7*6)+(6*1)+(5*0)+(4*3)+(3*1)+(2*8)+(1*3)=82
82 % 10 = 2
So 61031-83-2 is a valid CAS Registry Number.

SITE SELECTIVE CYCLOADDITION REACTION OF 1-METHOXY-1-TRIMETHYLSILOXY-1,3,5-HEXATRIENE WITH DIENOPHILE
Ohno, Masatomi,Mori, Kohki,Eguchi, Shoji
, p. 3381 - 3384 (2007/10/02)
The Diels-Alder reaction of the title triene occurred at the site of C-3-C-6 rather than of intuitively favored C-1-C-4, as the result of the prevailing steric effect over the orbital effect.
