Check Digit Verification of cas no

The CAS Registry Mumber 1021442-94-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,2,1,4,4 and 2 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1021442-94:
(9*1)+(8*0)+(7*2)+(6*1)+(5*4)+(4*4)+(3*2)+(2*9)+(1*4)=93
93 % 10 = 3
So 1021442-94-3 is a valid CAS Registry Number.

Palladium-catalyzed alcoholysis of 3-iodopropynamides: Selective synthesis of carbamoylacetates

Tang, Jian-Sheng,Guo, Can-Cheng

, p. 108 - 112 (2015)

A novel and selective method for the synthesis of carbamoylacetates via the alcoholysis of 3-iodopropynamides has been developed. 3-Iodopropynamides react with alcohols in the presence of palladium(II) acetate and DABCO to afford the corresponding carbamoylacetates in moderate to good yields.

PhI(OCOCF3)2-Mediated Construction of a 2-Spiropseudoindoxyl Skeleton via Cascade Annulation of 2-Sulfonamido-N-phenylpropiolamide Derivatives

Zhang, Bobo,Zhang, Xiang,Hu, Bei,Sun, Desong,Wang, Senlin,Zhang-Negrerie, Daisy,Du, Yunfei

supporting information, p. 902 - 905 (2017/02/26)

A cascade annulation of 2-sulfonamido-N-phenylpropiolamide derivatives leading to the construction of the 2-spiropseudoindoxyl skeleton was realized under mild conditions with phenyliodine(III) bis(trifluoroacetate) (PIFA) as the sole oxidant. This metal-
