5751-45-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 5751-45-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,7,5 and 1 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 5751-45:
(6*5)+(5*7)+(4*5)+(3*1)+(2*4)+(1*5)=101
101 % 10 = 1
So 5751-45-1 is a valid CAS Registry Number.

Olefination of carbonyl compounds through reductive coupling of alkenylboronic acids and tosylhydrazones

Perez-Aguilar, M. Carmen,Valdes, Carlos

supporting information; experimental part, p. 5953 - 5957 (2012/07/30)

The partners decide: The C-C bond-forming reductive cross-coupling of alkenylboronic acids and tosylhydrazones takes place under mild reaction conditions without the need of a metal catalyst, thus giving rise to olefination-type products (see scheme). The position of the double bond in the product is determined by the structure of the coupling partners. Copyright
