Check Digit Verification of cas no

The CAS Registry Mumber 1354701-45-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,5,4,7,0 and 1 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1354701-45:
(9*1)+(8*3)+(7*5)+(6*4)+(5*7)+(4*0)+(3*1)+(2*4)+(1*5)=143
143 % 10 = 3
So 1354701-45-3 is a valid CAS Registry Number.

Direct Conversion of Aldehydes and Ketones into Azides by Sequential Nucleophilic Addition and Substitution

Goswami, Pratik P.,Suding, Victoria P.,Carlson, Angela S.,Topczewski, Joseph J.

, p. 4805 - 4809 (2016)

This report describes the direct conversion of aldehydes and ketones into alkyl azides by the addition of common organometallic reagents and tandem conversion of the resulting alkoxides without isolation of the intermediate alcohols. A wide range of aldehydes and organometallic reagents (R–Li or R–MgX) are suitable participants in this process. Additional reaction telescoping beyond azide formation is demonstrated.

Direct catalytic azidation of allylic alcohols

Rueping, Magnus,Vila, Carlos,Uria, Uxue

supporting information; experimental part, p. 768 - 771 (2012/03/26)

A direct catalytic azidation of primary, secondary, and tertiary allylic alcohols has been developed. This new azidation reaction affords the corresponding allylic azides in high to excellent yields and regioselectivities. The reaction provides straightforward access to allylic azides that are valuable intermediates in organic synthesis, including the preparation of primary amines or 1,2,3-triazole derivatives.
