(8*1)+(7*1)+(6*7)+(5*8)+(4*5)+(3*8)+(2*8)+(1*4)=161
161 % 10 = 1
So 117858-84-1 is a valid CAS Registry Number.

POLYHYDROXYLATED PYRROLIDINES FROM SUGAR LACTONES: SYNTHESIS OF 1,4-DIDEOXY-1,4-IMINO-D-GLUCITOL FROM D-GALACTONOLACTONE AND SYNTHESES OF 1,4-DIDEOXY-1,4-IMINO-D-ALLITOL, 1,4-DIDEOXY-1,4-IMINO-D-RIBITOL, AND (2S,3R,4S)-3,4-DIHYDROXYPROLINE FROM D-GULONOLACTONE

Fleet, George W. J.,Son, Jong Chan

, p. 2637 - 2648 (1988)

The use of readily available sugar lactones in the synthesis of polyhydroxylated pyrrolidines is illustrated by the preparation of the glucosidase inhibitor 1,4-dideoxy-1,4-imino-D-glucitol from D-galactonolactone and by the conversion of D-gulonolactone into 1,4-dideoxy-1,4-imino-D-allitol, 1,4-dideoxy-1,4-imino-D-ribitol, and (2S,3R,4S)-3,4-dihydroxyproline.
