1400655-49-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1400655-49-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,0,0,6,5 and 5 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1400655-49:
(9*1)+(8*4)+(7*0)+(6*0)+(5*6)+(4*5)+(3*5)+(2*4)+(1*9)=123
123 % 10 = 3
So 1400655-49-3 is a valid CAS Registry Number.

Total synthesis of laetevirenol A
Choi, Young Lok,Kim, Bum Tae,Heo, Jung-Nyoung
, p. 8762 - 8767,6 (2020/09/15)
The first complete synthesis of laetevirenol A was performed in nine steps via intramolecular Friedel-Crafts alkylation in a trans-selective manner. The key phenanthrene intermediate was synthesized by a one-pot Suzuki-Miyaura coupling and an aldol condensation cascade reaction.
