133086-79-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 133086-79-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,3,0,8 and 6 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 133086-79:
(8*1)+(7*3)+(6*3)+(5*0)+(4*8)+(3*6)+(2*7)+(1*9)=120
120 % 10 = 0
So 133086-79-0 is a valid CAS Registry Number.

An efficient 'one pot'synthesis of isoflavones
Balasubramanian, Sreenivasan,Nair, Muraleedharan G.
, p. 469 - 484 (2000)
Initial formation of deoxybenzoin 3 from phenyl acetic acid 1 and phenol 2 in the presence of BF3.Et2O followed by its treatment at room temperature with N, N'-dimethyl (chloromethylene) ammonium chloride, generated by reacting PCl5 with DMF provides a mild and efficient route for a 'one pot' synthesis of Isoflavones in high yields.
