Check Digit Verification of cas no

The CAS Registry Mumber 197449-37-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,7,4,4 and 9 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 197449-37:
(8*1)+(7*9)+(6*7)+(5*4)+(4*4)+(3*9)+(2*3)+(1*7)=189
189 % 10 = 9
So 197449-37-9 is a valid CAS Registry Number.

A Chemo-Enzymatic Synthesis of D-Allosamine Derivatives from Tri-O-acetyl- D-glucal

Sugai, Takeshi,Okazaki, Hanako,Kuboki, Atsuhito,Ohta, Hiromichi

, p. 2535 - 2540 (1997)

N-Acetyl-D-allosamine and its derivatives were synthesized from tri-O-acetyl-D-glucal based on lipase-catalyzed selective protection of primary alcohols, [3,3] sigmatropic rearrangement of allylic trichloroacetimidates, and stereo- selective ruthenium-catalyzed dihydroxylation. In the course of this study, it was revealed that the Pseudomonas lipase- catalyzed acetylation occurred in a high yield (> 90%) exclusively at the primary alcohols of three Ferrier rearrangement products derived from tri-O-acetyl-D-glucal.
