Check Digit Verification of cas no

The CAS Registry Mumber 66696-96-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,6,6,9 and 6 respectively; the second part has 2 digits, 9 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 66696-96:
(7*6)+(6*6)+(5*6)+(4*9)+(3*6)+(2*9)+(1*6)=186
186 % 10 = 6
So 66696-96-6 is a valid CAS Registry Number.

Oxone-promoted hydration of electron-deficient allenic esters and ketones into 1,3-dicarbonyl compounds

Yi, Yu-Ping,Zheng, Yan,Nie, Jing,Ma, Jun-An

, p. 4523 - 4526 (2015)

Abstract A novel and mild protocol for the hydration of electron-deficient allenic esters and ketones into various 1,3-dicarbonyl compounds is described. The hydration of allenes promoted by oxone in DMF afforded the corresponding products in moderate to good yields. This work features the employment of only a catalytic amount of inexpensive and nontoxic solid reagent oxone (2KHSO5·KHSO4·K2SO4), avoiding the utility of toxic metals or traditional Br?nsted acids, in a green version of viewpoint. A possible reaction mechanism for this transformation is also primarily proposed.
