The CAS Registry Mumber 1554668-40-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,5,5,4,6,6 and 8 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1554668-40:
(9*1)+(8*5)+(7*5)+(6*4)+(5*6)+(4*6)+(3*8)+(2*4)+(1*0)=194
194 % 10 = 4

An expedient synthesis of 3-alkylideneoxindoles by Ti(OiPr) 4/pyridine-mediated Knoevenagel condensation

Lee, Hyun Ju,Lim, Jin Woo,Yu, Jin,Kim, Jae Nyoung

, p. 1183 - 1187 (2014/02/14)

3-Alkylideneoxindoles have been prepared in excellent yields from oxindole and carbonyl compounds via an in situ generated titanium enolate of oxindole. (Z)-3-Alkylideneoxindoles could be synthesized selectively as major products from unsymmetrical ketones.
