Check Digit Verification of cas no

The CAS Registry Mumber 98698-57-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,8,6,9 and 8 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 98698-57:
(7*9)+(6*8)+(5*6)+(4*9)+(3*8)+(2*5)+(1*7)=218
218 % 10 = 8
So 98698-57-8 is a valid CAS Registry Number.

ALDOL CONDENSATIONS OF ETHYL 1,3-DITHIOLANE-2-CARBOXYLATE AND ETHYL 1,3-DITHIANE-2-CARBOXYLATE WITH CHIRAL ALDEHYDES. EXCEPTIONAL DIASTEREOFACE SELECTIVITY FROM TWO CONVENIENT ACETATE EQUIVALENTS.

Flippin, Lee A.,Dombroski, Mark A.

, p. 2977 - 2980 (1985)

Lithium enolates derived from the title esters show high diastereoface selectivity in their reactions with chiral aldehydes.The resulting 2,2-dithioaldols are desulfurized in good yield with Ni2B-H2 (EtOH, 20 deg C).With this mild desulfurization protocol, complete retention of stereochemical integrity was observed for all isolated aldols.
