Check Digit Verification of cas no

The CAS Registry Mumber 97961-97-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,7,9,6 and 1 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 97961-97:
(7*9)+(6*7)+(5*9)+(4*6)+(3*1)+(2*9)+(1*7)=202
202 % 10 = 2
So 97961-97-2 is a valid CAS Registry Number.

SYNTHESIS OF 1'-(3-DIMETHYLAMINOPROPYL)-2'-SUBSTITUTED SPIRO.

Rodriguez, Jose-Gonzalo,Temprano, Fernando

, p. 3243 - 3248 (2007/10/02)

Reactivity of the C=N bond in spiro has been analysed.Indolines were obtained in practically quantitative yield using organomagnesium reagents in the presence of copper(I) chloride in toluene at 120 deg C.On the basis of an an

REACTION OF SPIRO WITH GRIGNARD REAGENTS IN THE PRESENCE OF CUPROUS CHLORIDE

Rodriguez, Gonzalo,Benito, Yolanda,Temprano, Fernando

, p. 427 - 428 (2007/10/02)

Attack of MeMgI and PhMgBr in toluene on spiro (1) in the presence of Cu2Cl2 gives 2'-substituted spiro in quantitative yields.Also, attack of PhCH2CH2MgBr on 1 in the presence of Cu2Cl2 afforded 2'-phenethyl, 2'-H and 2'-benzyl (or 2'-p-xylyl) derivatives in toluene (or p-xylene) as solvent.
