904313-97-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 904313-97-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,0,4,3,1 and 3 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 904313-97:
(8*9)+(7*0)+(6*4)+(5*3)+(4*1)+(3*3)+(2*9)+(1*7)=149
149 % 10 = 9
So 904313-97-9 is a valid CAS Registry Number.

Using stereoelectronic effects to explain selective reactions of 4-substituted five-membered ring oxocarbenium ions
Smith, Deborah M.,Woerpel
, p. 2063 - 2066 (2007/10/03)
Equation presented. The utility of the inside attack model to predict and analyze the stereoselectivities of nucleophilic additions to complex five-membered ring oxocarbenium ions is demonstrated in a systematic study of C-4-substituted acetals.
