Check Digit Verification of cas no

The CAS Registry Mumber 918123-65-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,1,8,1,2 and 3 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 918123-65:
(8*9)+(7*1)+(6*8)+(5*1)+(4*2)+(3*3)+(2*6)+(1*5)=166
166 % 10 = 6
So 918123-65-6 is a valid CAS Registry Number.

Reaction of nitroorganic compounds using thiourea catalysts anchored to polymer support

Miyabe, Hideto,Tuchida, Sayo,Yamauchi, Masashige,Takemoto, Yoshiji

, p. 3295 - 3300 (2008/09/17)

Immobilization of chiral thiourea catalyst was studied. The PEG-bound thiourea showed better catalytic activity than those of the carboxypolystyrene HL resin-bound and TentaGel carboxy resin-bound thioureas. In the presence of PEG-bound thiourea, Michael and tandem Michael reactions of trans-β- nitrostyrene proceeded enantioselectively. Georg Thieme Verlag Stuttgart.
