129797-19-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 129797-19-9 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 7 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 129797-19:
(8*1)+(7*2)+(6*9)+(5*7)+(4*9)+(3*7)+(2*1)+(1*9)=179
179 % 10 = 9
So 129797-19-9 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
