Check Digit Verification of cas no

The CAS Registry Mumber 101689-08-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,1,6,8 and 9 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 101689-08:
(8*1)+(7*0)+(6*1)+(5*6)+(4*8)+(3*9)+(2*0)+(1*8)=111
111 % 10 = 1
So 101689-08-1 is a valid CAS Registry Number.

SYNTHESIS OF THE RACEMIC FORM OF (Z)-1,17-DIAMINOOCTADEC-9-ENE, AN ALIPHATIC DIAMINE FROM COCCINELLIDAE. DETERMINATION OF THE ABSOLUTE CONFIGURATION OF THE (+)-NATURALLY-OCCURRING ANTIPODE

Braconnier, M.F.,Braekman, J.C.,Daloze, D.

, p. 605 - 614 (2007/10/02)

The total synthesis of the title compound (1) has been achieved.Also reported is the use of lanthanide induced shifts in 1H NMR spectroscopy to assign the absolute configuration of the α-carbon atom in chiral primary α-methylalkylamines.Application of this empirical method to natural (+)-1 shows that it has the R-configuration at C-17.
