Check Digit Verification of cas no

The CAS Registry Mumber 1218793-46-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,1,8,7,9 and 3 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1218793-46:
(9*1)+(8*2)+(7*1)+(6*8)+(5*7)+(4*9)+(3*3)+(2*4)+(1*6)=174
174 % 10 = 4
So 1218793-46-4 is a valid CAS Registry Number.

Chemoselective SN2′ reaction of nitroalkanes to dialkyl 2-(bromomethyl)fumarates under cetyltrimethylammonium hydroxide (CTAOH) catalysis

Ballini, Roberto,Gabrielli, Serena,Palmieri, Alessandro

scheme or table, p. 1233 - 1235 (2010/04/25)

The chemoselective SN2′ reaction of a variety of primary nitroalkanes to dialkyl 2-(bromomethyl)fumarates can be efficiently performed under cetyltrimethylammonium hydroxide (CTAOH) catalysis. The α,β-unsaturated esters were obtained in satisfactory to good yields with the complete retention of the nitro group.
