254446-98-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 254446-98-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,5,4,4,4 and 6 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 254446-98:
(8*2)+(7*5)+(6*4)+(5*4)+(4*4)+(3*6)+(2*9)+(1*8)=155
155 % 10 = 5
So 254446-98-5 is a valid CAS Registry Number.

The platinum catalysed diboration of alkynes using 1,2- B2Cl2(NMe2)2: Formation of 1-azonia-2-borata-5-borole derivatives
Anderson,Lesley,Norman,Orpen,Starbuck
, p. 1053 - 1055 (2008/10/08)
The platinum catalysed diboration of alkynes using the diborane(4) compound 1,2-B2Cl2(NMe2)2 affords high yields of cyclic 1-azonia-2- borata-5-borole compounds, which arise from redistribution of B-Cl and B- NMe2 bonds.
