129796-99-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 129796-99-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,9,7,9 and 6 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 129796-99:
(8*1)+(7*2)+(6*9)+(5*7)+(4*9)+(3*6)+(2*9)+(1*9)=192
192 % 10 = 2
So 129796-99-2 is a valid CAS Registry Number.

Oxirane Ring Opening of Anhydrosugars with Alkynyl- and Alkenylaluminates
Inghardt, Tord,Frejd, Torbjoern
, p. 285 - 291 (2007/10/02)
The oxirane ring opening of 2,3-anhydro-pentopyranosides and 2,3-anhydro-hexopyranosides with organoaluminate reagents is described.By the use of trialkylalkynylaluminates, deoxy-alkynyl sugars are obtained in good yields.Trialkylalkenylaluminates are les
