237404-18-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 237404-18-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,3,7,4,0 and 4 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 237404-18:
(8*2)+(7*3)+(6*7)+(5*4)+(4*0)+(3*4)+(2*1)+(1*8)=121
121 % 10 = 1
So 237404-18-1 is a valid CAS Registry Number.

A silyl-mediated [3+2] photochemical cycloaddition
Organ, Michael G.,Mallik, Debasis
, p. 1259 - 1262 (2008/01/27)
The generation of larger rings from intermediate cyclobutanes via a two-step [2+2] photocycloaddition - ring expansion, known as the de Mayo reaction, has been widely applied in synthesis. Herein a one-step synthesis of cyclopentanoids has been developed
