307972-91-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 307972-91-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,0,7,9,7 and 2 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 307972-91:
(8*3)+(7*0)+(6*7)+(5*9)+(4*7)+(3*2)+(2*9)+(1*1)=164
164 % 10 = 4
So 307972-91-4 is a valid CAS Registry Number.

Mild reductive opening of aryl pyranosides promoted by scandium(III) triflate
Qin, Hua-Li,Lowe, Jason T.,Panek, James S.
, p. 38 - 39 (2007/10/03)
An efficient method for the nucleophilic ring opening of stereochemically well-defined aryl pyranosides is described. The reaction effects a formal deoxygenation of the benzylic position to provide useful, enantioenriched building blocks. To illustrate th
