Check Digit Verification of cas no

The CAS Registry Mumber 1644148-26-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,4,4,1,4 and 8 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1644148-26:
(9*1)+(8*6)+(7*4)+(6*4)+(5*1)+(4*4)+(3*8)+(2*2)+(1*6)=164
164 % 10 = 4
So 1644148-26-4 is a valid CAS Registry Number.

Ethenolate transfer reactions: A facile synthesis of vinyl esters

Appaye, Srinivasan Kaliyaperumal,Nikumbh, Satish Pandurang,Govindapur, Rajeshwar Reddy,Banerjee, Shyamapada,Bhalerao, Dinesh S.,Kumar, Unniaran K. Syam

, p. 1115 - 1122 (2014)

A simple and efficient metal-free ethenolate transfer reaction has been elaborated in moderate-to-high yields from vinyl acetate. This reaction was accomplished by generation of potassium ethenolate, which was then reacted with homo and mixed anhydrides of aliphatic, aryl and heteroaryl acids, to yield the corresponding vinyl esters. The utility of thus generated vinyl esters was then probed by carrying out intramolecular Heck reactions to give isobenzofuran-1(3H)-one derivatives in excellent yields. Copyright
