Check Digit Verification of cas no

The CAS Registry Mumber 1021934-07-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,2,1,9,3 and 4 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1021934-07:
(9*1)+(8*0)+(7*2)+(6*1)+(5*9)+(4*3)+(3*4)+(2*0)+(1*7)=105
105 % 10 = 5
So 1021934-07-5 is a valid CAS Registry Number.

Regio-and stereoselective hydroxybromination and dibromination of olefins using ammonium bromide and oxone

MacHarla, Arun Kumar,Chozhiyath Nappunni, Rohitha,Nama, Narender

supporting information; experimental part, p. 1401 - 1405 (2012/04/04)

An efficient protocol for the synthesis of vicinal bromohydrins and dibromides from olefins is presented. Various olefins are regio-and stereoselectively hydroxybrominated and dibrominated with anti fashion, following Markonikov's rule, using eco-friendly, non-toxic, and stable reagents such as NH4Br and oxone in CH3CN/H2O (1:1) and CH3CN without employing catalyst in moderate to excellent yields. Bromohydrins are formed instantaneously.
