73110-65-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 73110-65-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,3,1,1 and 0 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 73110-65:
(7*7)+(6*3)+(5*1)+(4*1)+(3*0)+(2*6)+(1*5)=93
93 % 10 = 3
So 73110-65-3 is a valid CAS Registry Number.

Tosylhydrazine mediated conjugate reduction and sequential reductive coupling cyclization: Synthesis of 2-arylchromans

Shang, Xuyang,Zhou, Xiaomeng,Zhang, Wei,Wan, Changfeng,Chen, Junmin

, p. 8187 - 8193 (2015/12/30)

Tosylhydrazine mediated conjugate reduction of 2-hydroxyl chalcones and sequential reductive coupling cyclization is described. This is an unprecedented protocol and an extremely efficient method for a one-pot domino synthesis of 2-arylchromans in good to excellent yields from commercially available, cheap starting materials. More importantly, the two-step reactions can be easily controlled to afford dihydrochalcones or 2-arylchromans by the mole amounts of tosylhydrazine. Furthermore, the operational simplicity of the process and the high functional group tolerance are remarkable.
