Check Digit Verification of cas no

The CAS Registry Mumber 1613073-72-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,1,3,0,7 and 3 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1613073-72:
(9*1)+(8*6)+(7*1)+(6*3)+(5*0)+(4*7)+(3*3)+(2*7)+(1*2)=135
135 % 10 = 5
So 1613073-72-5 is a valid CAS Registry Number.

Cascade nitrosation and addition-elimination of nitroacetanilides for the highly efficient synthesis of 1,4,2,5-dioxadiazine derivatives

Mo, Shanyan,Huang, Peipei,Xu, Jiaxi

, p. 4192 - 4200 (2014/06/10)

A domino nitrosation and addition-elimination of nitroacetanilides with NaNO2 and H2SO4 has been developed to synthesize a variety of 1,4,2,5-dioxadiazine-3,6-dicarboxamides in excellent yields. The substrate scope can be extended to aryl nitromethyl ketones. A cascade reaction mechanism is proposed and the conjugated aryl moiety is considered to help stabilize the aci-nitroso species, the key intermediates in the cascade reaction. The methodology is practical and efficient because it avoids the purification of the intermediates. The nitroacetanilides were prepared from nitroacetic acid and various anilines employing DCC-DMAP as coupling reagents, and this protocol also possesses advantages like easy handling and high yields.
