Check Digit Verification of cas no

The CAS Registry Mumber 188640-86-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,8,6,4 and 0 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 188640-86:
(8*1)+(7*8)+(6*8)+(5*6)+(4*4)+(3*0)+(2*8)+(1*6)=180
180 % 10 = 0
So 188640-86-0 is a valid CAS Registry Number.

Diastereoselective propargylation of sugar aldehydes. New synthesis of 6-deoxyheptoses

Pakulski, Zbigniew,Zamojski, Aleksander

, p. 2653 - 2666 (1997)

Propargylation of pentofuranose aldehydes by treatment with propargyl bromide in the presence of zinc dust yielded homopropargylic alcohols with a good isolated yield and, in many cases, excellent anti/syn selectivity. Catalytic hydrogenation of the triple bond afforded homoallylic alcohols, valuable substrates for the synthesis of 6-deoxyheptoses. Direct ozonolysis of the triple bond yielded uronic acid esters.
