Check Digit Verification of cas no

The CAS Registry Mumber 1431932-77-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,3,1,9,3 and 2 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1431932-77:
(9*1)+(8*4)+(7*3)+(6*1)+(5*9)+(4*3)+(3*2)+(2*7)+(1*7)=152
152 % 10 = 2
So 1431932-77-2 is a valid CAS Registry Number.

Thermal Rearrangement of Sulfamoyl Azides: Reactivity and Mechanistic Study

Zou, Xiaodong,Zou, Jiaqi,Yang, Lizheng,Li, Guigen,Lu, Hongjian

, p. 4677 - 4688 (2017/05/12)

The rearrangement of sulfamoyl azides under thermal conditions to form a C-C bond while breaking two C-N bonds is reported. Mechanistic study shows that this reaction goes through a Curtius-type rearrangement to form a 1,1-diazene, then which rearranges possibly through both a concerted rearrangement process and a stepwise radical process. This rearrangement could be used in the synthesis of complex biologically active molecules, such as sterols, and piperine derivatives.
