872676-56-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 872676-56-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,7,2,6,7 and 6 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 872676-56:
(8*8)+(7*7)+(6*2)+(5*6)+(4*7)+(3*6)+(2*5)+(1*6)=217
217 % 10 = 7
So 872676-56-7 is a valid CAS Registry Number.

Asymmetric synthesis of α- and α,β-substituted β-alkoxycarbonyl sulfonates
Enders, Dieter,Adelbrecht, Jean-Claude,Harnying, Wacharee
, p. 2962 - 2968 (2005)
An efficient asymmetric synthesis of substituted β-alkoxycarbonyl sulfonates is described. Enantiopure α-substituted β-alkoxycarbonyl sulfonates can be obtained via α-alkylation of metalated sulfonates bearing 1,2:5,6-di-O-isopropylidene-α-D-allofuranose
