Check Digit Verification of cas no

The CAS Registry Mumber 1021179-00-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,2,1,1,7 and 9 respectively; the second part has 2 digits, 0 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1021179-00:
(9*1)+(8*0)+(7*2)+(6*1)+(5*1)+(4*7)+(3*9)+(2*0)+(1*0)=89
89 % 10 = 9
So 1021179-00-9 is a valid CAS Registry Number.

PREPARATION AND USE OF MAGNESIUM AMIDES

-

Page/Page column 30-31, (2008/12/07)

The present application relates to mixed Mg/Li amides of the general formula R1R2N-Mg-NR3R4.zLiY (II) wherein R1, R2, R3, and R4 are, independently, selected from H, substituted or unsubstituted aryl or heteroaryl containing one or more heteroatoms, linear, branched or cyclic, substituted or unsubstituted alkyl, alkenyl, alkynyl, or silyl derivatives thereof; and R1 and R2 together, or R3 and R4 together can be part of a cyclic or polymeric structure; and wherein at least one of R1 and R2 and at least one of R3 and R4 is other than H; Y is selected from the group consisting of F; Cl; Br; I; CN; SCN; NCO; HaIOn, wherein n = 3 or 4 and Hal is selected from Ci, Br and I; NO3; BF4; PF6; H; a carboxylate of the general formula RxCO2; an alcoholate of the general formula ORx; a thiolate of the general formula SRx; RxP(O)O2; or SCORx; or SCSRx; OnSRx, wherein n = 2 or 3; or NOn, wherein n = 2 or 3; and a derivative thereof; wherein Rx is a substituted or unsubstituted aryl or heteroaryl containing one or more heteroatoms, linear, branched or cyclic, substituted or unsubstituted alkyl, alkenyl, alkynyl, or derivatives thereof, or H; m is O or 1; and z > 1; as well as a process for the preparation of the mixed Mg/Li amides and the use of these amides, e.g. as bases.
