65050-57-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 65050-57-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,5,0,5 and 0 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 65050-57:
(7*6)+(6*5)+(5*0)+(4*5)+(3*0)+(2*5)+(1*7)=109
109 % 10 = 9
So 65050-57-9 is a valid CAS Registry Number.

A study of the reactions of 1,3-diynes with organo-cuprates and -argentates
Kleijn, H.,Tigchelaar, M.,Meijer, J.,Vermeer, P.
, p. 337 - 341 (2007/10/02)
1,3-Diynes HCC-CC-R' (1, R'= H or Ph) are converted by cuprates M' (R = alkyl; Y = Cl, Br or R; M'= Li, MgCl or MgBr) into a mixture of C-R'>M' (2) and C-R'>M' (3).When R is n-alkyl, adducts 2 are the major pr
