Check Digit Verification of cas no

The CAS Registry Mumber 1402242-70-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,0,2,2,4 and 2 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1402242-70:
(9*1)+(8*4)+(7*0)+(6*2)+(5*2)+(4*4)+(3*2)+(2*7)+(1*0)=99
99 % 10 = 9
So 1402242-70-9 is a valid CAS Registry Number.

Synthesis of ynone trifluoroborates toward functionalized pyrazoles

Kirkham, James D.,Edeson, Steven J.,Harrity, Joseph P. A.,Stokes, Stephen

, p. 5354 - 5357,4 (2012/12/12)

The synthesis of a range of novel ynone trifluoroborates has been achieved, in a two-pot process from propargylic alcohols. These alkynes have been subsequently used in the formation of a range of pyrazole trifluoroborate salts via cyclization with hydrazines. The products are generated with high levels of regiocontrol and in excellent yields and represent versatile synthetic intermediates.
