Check Digit Verification of cas no

The CAS Registry Mumber 866871-73-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,6,6,8,7 and 1 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 866871-73:
(8*8)+(7*6)+(6*6)+(5*8)+(4*7)+(3*1)+(2*7)+(1*3)=230
230 % 10 = 0
So 866871-73-0 is a valid CAS Registry Number.

Organocatalytic 1,3-Dipolar Cycloaddition Reaction of β-Keto Amides with Azides - Direct Access to 1,4,5-Trisubstituted 1,2,3-Triazole-4-carboxamides

Zhou, Xiao,Xu, Xianhong,Liu, Kun,Gao, Hua,Wang, Wei,Li, Wenjun

supporting information, p. 1886 - 1890 (2016/05/09)

Organocatalytic [3+2] 1,3-dipolar cycloaddition reactions of β-keto amides with azides catalyzed by 1,8-diazabicyclo[5.4.0]undec-7-ene (DBU) have been developed. This strategy generates 1,4,5-trisubstituted 1,2,3-triazole-4-carboxamides in high yields and

Intramolecular hydrogen bonding-assisted cyclocondensation of α-diazoketones with various amines: A strategy for highly efficient Wolff 1,2,3-triazole synthesis

Wang, Zikun,Bi, Xihe,Liao, Peiqiu,Zhang, Rui,Liang, Yongjiu,Dong, Dewen

, p. 7076 - 7078 (2012/08/14)

A catalytic and highly efficient Wolff's cyclocondensation of α-diazoketones with aromatic and aliphatic amines has been realized for the first time by utilizing the strategy of an intramolecular hydrogen bonding-activating carbonyl group. This approach successfully solved the challenging problem of poor condensation efficiency in Wolff 1,2,3-triazole synthesis, and constitutes a powerful method for the synthesis of highly functionalized 1,2,3-triazoles.
