Check Digit Verification of cas no

The CAS Registry Mumber 93728-41-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,3,7,2 and 8 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 93728-41:
(7*9)+(6*3)+(5*7)+(4*2)+(3*8)+(2*4)+(1*1)=157
157 % 10 = 7
So 93728-41-7 is a valid CAS Registry Number.

Copper-catalyzed regiodivergent 1,4-and 1,6-conjugate silyl addition to diendioates: Access to functionalized allylsilanes

Ahmad, Tanveer,Li, Qi,Qiu, Sheng-Qi,Xu, Jian-Lin,Xu, Yun-He,Loh, Teck-Peng

, p. 6122 - 6126 (2019)

A copper-catalyzed regioselective 1,4-and 1,6-conjugate addition of a silyl reagent to diendioates was established. Various 1,4-and 1,6-protosilylation products were obtained in good yields and with high regioselectivity via tuning the ligands used in the reactions. This protocol has provided a simple and efficient method for the synthesis of multisubstituted functionalized allylsilanes.
