Check Digit Verification of cas no
The CAS Registry Mumber 143697-03-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,3,6,9 and 7 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 143697-03:
(8*1)+(7*4)+(6*3)+(5*6)+(4*9)+(3*7)+(2*0)+(1*3)=144
144 % 10 = 4
So 143697-03-4 is a valid CAS Registry Number.

Promoting reductive tandem reactions of nitrostyrenes with Mo(CO)6 and a palladium catalyst to produce 3 h -indoles

The combination of Mo(CO)6 and 10 mol % of palladium acetate catalyzes the transformation of 2-nitroarenes to 3H-indoles through a tandem cyclization-[1,2] shift reaction of in situ generated nitrosoarenes. Mo(CO)6 appears to have dual roles in this transformation: generate CO and promote C-N bond formation to increase the yield of the N-heterocycle product.
A facile and convenient synthesis of functionalized ortho- nitrophenylboronic acids
Collibee, Scott E.,Yu, Jiaxin
, p. 4453 - 4455 (2007/10/03)
A variety of ortho-nitrophenylboronic acids bearing functional groups such as cyano, nitro, halo, α-bromomethyl, and ester were prepared in good yields via I-Mg exchange followed by quenching with trimethyl borate. All reagents employed in this procedure are commercially available and were used without further purification, and the procedure can be executed in about an hour.
