838-98-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 838-98-2 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 8,3 and 8 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 838-98:
(5*8)+(4*3)+(3*8)+(2*9)+(1*8)=102
102 % 10 = 2
So 838-98-2 is a valid CAS Registry Number.

A facile method for the preparation of carbodiimides from thioureas and (Boc)2O

Wu, He,Sun, Yan-Fang,Zhang, Chen,Miao, Chun-Bao,Yang, Hai-Tao

, p. 739 - 742 (2018/01/27)

A concise method for the preparation of carbodiimides from thioureas using di-tert-butyl dicarbonate [(Boc)2O] as the dehydrosulfurizative reagent has been developed. Using DMAP as the catalyst, a variety of symmetric and asymmetric 1,3-diaryl thioureas were converted into the corresponding carbodiimides efficiently in a short time.

"On water": Efficient iron-catalyzed cycloaddition of aziridines with heterocumulenes

Sengoden, Mani,Punniyamurthy, Tharmalingam

supporting information, p. 572 - 575 (2013/02/23)

In suspension: The reaction of aziridines with heterocumulenes in the presence of Fe(NO3)3×9 H2O in aqueous suspension provides access to functionalized five-membered heterocycles in good to high yields. This protocol has a wide substrate scope, is simple, and uses a nontoxic and cheap catalyst. Copyright

Manganese-catalyzed cleavage of a carbon-carbon single bond between carbonyl carbon and α-carbon atoms of ketones

Kuninobu, Yoichiro,Uesugi, Tadamasa,Kawata, Atsushi,Takai, Kazuhiko

supporting information; experimental part, p. 10406 - 10408 (2011/12/04)

Singled out: Treatment of ketones with carbodiimides in the presence of a catalytic amount of either [{HMn(CO)4}3] or [Mn 2(CO)10] gave amides in good to excellent yields. In this reaction, the carbon-carbon single bond of a ketone is cleaved efficiently. The reaction also proceeded by using isocyanates instead of carbodiimides. Copyright
