Check Digit Verification of cas no

The CAS Registry Mumber 77198-20-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,1,9 and 8 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 77198-20:
(7*7)+(6*7)+(5*1)+(4*9)+(3*8)+(2*2)+(1*0)=160
160 % 10 = 0
So 77198-20-0 is a valid CAS Registry Number.

Microwave-Assisted Cp*CoIII-Catalyzed C-H Activation/Double C-N Bond Formation Reactions to Thiadiazine 1-Oxides

Huang, Jiapian,Huang, Yangfei,Wang, Tao,Huang, Qin,Wang, Zhihua,Chen, Zhiyuan

, p. 1128 - 1131 (2017)

A microwave-assisted, Cp*CoIII-catalyzed direct C-H activation/double C-N bond formation reaction of simple NH-sulfoximines with 1,4,2-dioxazol-5-ones to produce diverse thiadiazine-1-oxides is reported. The reaction tolerates a broad range of functional groups under external oxidant-free conditions and only releases CO2 and H2O as the sole byproducts. The preliminary mechanistic studies revealed an electrophilic metalation pathway is likely involved in the reaction.
