Check Digit Verification of cas no

The CAS Registry Mumber 1762-80-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,7,6 and 2 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1762-80:
(6*1)+(5*7)+(4*6)+(3*2)+(2*8)+(1*0)=87
87 % 10 = 7
So 1762-80-7 is a valid CAS Registry Number.

Generation of Oxazolidine-2,4-diones Bearing Sulfur-Substituted Quaternary Carbon Atoms by Oxothiolation/Cyclization of Ynamides

Huang, Hai,Fan, Junzhen,He, Guangke,Yang, Zhimin,Jin, Xiaodong,Liu, Qi,Zhu, Hongjun

supporting information, p. 2532 - 2538 (2016/02/12)

A novel method for metal-free oxothiolation of ynamides to construct oxazolidine-2,4-diones bearing sulfur-substituted quaternary carbon atoms has been developed. It represents a rare C-O bond cleavage of ynamides, as well as a facile and tandem approach for the formation of C-O, C-S, and C-Cl bonds. This redox-neutral protocol can be applied to the synthesis of multisubstituted oxazolidine-2,4-diones with good chemoselectivity and good yields of isolated products under mild conditions.

Formation of α-chalcogenyl acrylamides through unprecedented chalcogen-mediated metal-free oxyfunctionalization of ynamides with DMSO as an oxidant

Huang, Hai,Tang, Luning,Liu, Qi,Xi, Yang,He, Guangke,Zhu, Hongjun

supporting information, p. 5605 - 5608 (2016/05/09)

A novel chalcogen-mediated oxyfunctionalization mode of ynamides for the synthesis of α-chalcogenyl acrylamides has been developed. Independent of metal catalysts, external oxidants and additives, this mild process afforded a range of structurally diverse
