219143-51-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 219143-51-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,9,1,4 and 3 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 219143-51:
(8*2)+(7*1)+(6*9)+(5*1)+(4*4)+(3*3)+(2*5)+(1*1)=118
118 % 10 = 8
So 219143-51-8 is a valid CAS Registry Number.

Metal-catalysed multiple boration of ketimines
Cameron, Thomas M.,Tom Baker,Westcott, Stephen A.
, p. 2395 - 2396 (2007/10/03)
Metal-catalysed addition of B2cat′2 (cat′ = 4-But-1,2-O2C6H3) to ketimines affords N-borylenamines and HBcat′. Analogous catalysed reactions of ketimines with HBcat′ in tetrahydrofuran affo
