Check Digit Verification of cas no

The CAS Registry Mumber 87989-12-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,7,9,8 and 9 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 87989-12:
(7*8)+(6*7)+(5*9)+(4*8)+(3*9)+(2*1)+(1*2)=206
206 % 10 = 6
So 87989-12-6 is a valid CAS Registry Number.

MACROHETEROCYCLES. XVI. SYNTHESIS OF MACROCYCLIC LACTONOLACTAMS AND THEIR ION-SELECTIVE CHARACTERISTICS

Bogat-skii, A.V.,Luk'yanenko, N.G.,Shapkin, V.A.,Popkov, Yu.A.,Nazarova, N.Yu.,Chernotkach, Z.A.

, p. 798 - 804 (2007/10/02)

Sewenteen new macrocyclic lactonolactams were obtained by the acylation of N,N'-dimethylpolyoxyalkanediamines with acid dichlorides in benzene under conditions of high dilution.The coefficients of cationic selectivity in the series of alkali and alkaline-earth metals were determined for them, and compounds which exhibit high calcium selectivity were found.
