Check Digit Verification of cas no

The CAS Registry Mumber 66127-06-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,6,1,2 and 7 respectively; the second part has 2 digits, 0 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 66127-06:
(7*6)+(6*6)+(5*1)+(4*2)+(3*7)+(2*0)+(1*6)=118
118 % 10 = 8
So 66127-06-8 is a valid CAS Registry Number.

Halotrifluoromethylation of 1,3-Enynes: Access to Tetrasubstituted Allenes

Huang, Jinfeng,Jia, Yimin,Li, Xiangyu,Duan, Jianli,Jiang, Zhong-Xing,Yang, Zhigang

supporting information, p. 2314 - 2319 (2021/04/05)

A highly regioselective copper-catalyzed 1,4-chloro- and bromotrifluoromethylation of 1,3-enynes has been presented for the first time, which affords an efficient transformation to access halo- and CF3-containing tetrasubstituted allene derivatives with good to excellent yield. This protocol is practical and convenient, in which a wide range of functional groups are compatible. Applications of this method for the gram-scale preparation and late-stage functionalization of biologically active molecules are also demonstrated.
