139932-27-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 139932-27-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,9,3 and 2 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 139932-27:
(8*1)+(7*3)+(6*9)+(5*9)+(4*3)+(3*2)+(2*2)+(1*7)=157
157 % 10 = 7
So 139932-27-7 is a valid CAS Registry Number.

Synthesis of sialic acid through aldol condensation of glucose with oxalacetic acid
Yamamoto,Teshima,Inami,Shiba
, p. 325 - 328 (2007/10/02)
N-Acetylneuraminic acid (sialic acid) 1 was synthesized through relatively short steps from D-glucose via a key intermediate 1,5-lactone derivative obtained from the pyranose isomer of the aldol condensation products of D-glucose with oxalacetic acid.
