Check Digit Verification of cas no

The CAS Registry Mumber 111931-16-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,1,9,3 and 1 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 111931-16:
(8*1)+(7*1)+(6*1)+(5*9)+(4*3)+(3*1)+(2*1)+(1*6)=89
89 % 10 = 9
So 111931-16-9 is a valid CAS Registry Number.

SYNTHESIS AND APPLICATION OF IMIDAZOLE DERIVATIVES. SYNTHESIS OF (1-METHYL-1H-IMIDAZOL-2-YL)METHANOL DERIVATIVES AND CONVERSION INTO CARBONYL COMPOUNDS

Ohta, Shunsaku,Hayakawa, Satoshi,Nishimura, Kazuko,Okamoto, Masao

, p. 1058 - 1069 (2007/10/02)

(1-methyl-2H-imidazol-2-yl)methanol derivatives ( 4 and 7 ) were prepared by treating carbonyl compounds with 2-lithio-1-methyl-1H-imidazole ( 2 ) or by treating 2-acyl-1H-imidazoles ( 3 ) with organometallic reagents or sodium borohydride.The alcohols ( 4 and 7 ) were convertible into the carbonyl compounds via the corresponding quaternary salts ( 8 and 10 ).The stable (1-methyl-1H-imidazol-2-yl)methanol system, , can be regarded as a masked form of the carbonyl group as well as a synthon of the group.Keywords - (1-methyl-1H-imidazol-2-yl)methanol; 2-acyl-1-methyl-1H-imidazole; carbonyl compound synthesis; β-ketoester; protecting group; latent functionality; symmetric ketone; dihydrojasmone
