Check Digit Verification of cas no

The CAS Registry Mumber 157427-91-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,7,4,2 and 7 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 157427-91:
(8*1)+(7*5)+(6*7)+(5*4)+(4*2)+(3*7)+(2*9)+(1*1)=153
153 % 10 = 3
So 157427-91-3 is a valid CAS Registry Number.

Catalytic Dealkylative Synthesis of Cyclic Carbamates and Ureas via Hydrogen Atom Transfer and Radical-Polar Crossover

Nagai, Takuya,Mimata, Nao,Terada, Yoshihiro,Sebe, Chikayoshi,Shigehisa, Hiroki

, p. 5522 - 5527 (2020)

Guided by the transition-metal hydrogen atom transfer and radical-polar crossover concepts, we developed a functional-group-tolerant and scalable method for the synthesis of cyclic carbamates and ureas, which are found in the structures of bioactive compo

Synthetic Studies on Dynemicin A. New Quinoline Synthesis for C, D and E Rings

Nishikawa, Toshio,Isobe, Minoru

, p. 5621 - 5632 (2007/10/02)

The important intermediates for the syntheses of dynemicin A model compounds were prepared by coupling between aryltin compounds and α-bromoenone derivatives in the presence of palladium catalyst.The products were transformed under acidic conditions to su
