5962-57-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 5962-57-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,9,6 and 2 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 5962-57:
(6*5)+(5*9)+(4*6)+(3*2)+(2*5)+(1*7)=122
122 % 10 = 2
So 5962-57-2 is a valid CAS Registry Number.

Copper-Catalyzed C5-H Sulfenylation of Unprotected 8-Aminoquinolines Using Sulfonyl Hydrazides

Yu, Qing,Yang, Yiming,Wan, Jie-Ping,Liu, Yunyun

, p. 11385 - 11391 (2018/09/06)

The synthesis of C5-sulfenylated 8-aminoquinolines using unprotected 8-aminoquinolines and sulfonyl hydrazides is achieved via the catalysis of CuI. The reactions are hypothesized to proceed via the Cu(I)-Cu(II)-Cu(I) catalytic processes induced by aerobic oxidation and single-electron transfer on the Cu(II)-8-aminoquinoline complex. This work discloses an unprecedented step-efficient method for the synthesis of C5-sulfenylated 8-aminoquinolines bearing a useful free NH2 group.
