1644077-55-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1644077-55-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,4,4,0,7 and 7 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1644077-55:
(9*1)+(8*6)+(7*4)+(6*4)+(5*0)+(4*7)+(3*7)+(2*5)+(1*5)=173
173 % 10 = 3
So 1644077-55-3 is a valid CAS Registry Number.

A highly stereoselective BF3·OEt2-promoted tandem hydroamination/glycosylation on glycal scaffolds has been developed to form propargyl 3-tosylamino-2,3-dideoxysugars in a one-pot manner. Subsequent construction of multivalent 3-tosy
