Check Digit Verification of cas no

The CAS Registry Mumber 1602935-10-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,0,2,9,3 and 5 respectively; the second part has 2 digits, 1 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1602935-10:
(9*1)+(8*6)+(7*0)+(6*2)+(5*9)+(4*3)+(3*5)+(2*1)+(1*0)=143
143 % 10 = 3
So 1602935-10-3 is a valid CAS Registry Number.

CuBr-promoted formal hydroacylation of 1-alkynes with glyoxal derivatives: An unexpected synthesis of 1,2-dicarbonyl-3-enes

Chen, Shufeng,Li, Xiaojie,Zhao, Haiying,Li, Baoguo

, p. 4137 - 4141 (2014)

An efficient and concise protocol has been developed for the highly regio- and stereoselective synthesis of E-1,2-dicarbonyl-3-ene derivatives by a copper-promoted reaction of 1-alkynes with α-carbonyl aldehydes in the presence of morpholine. The products obtained are believed as the formal hydroacylation of the triple bond.
