Check Digit Verification of cas no

The CAS Registry Mumber 120467-66-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,0,4,6 and 7 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 120467-66:
(8*1)+(7*2)+(6*0)+(5*4)+(4*6)+(3*7)+(2*6)+(1*6)=105
105 % 10 = 5
So 120467-66-5 is a valid CAS Registry Number.

SYNTHESIS OF JUVABIONE ANALOGUES

Mane, Ramchandra B.,Desai, Uday V.,Hebbalkar, Geeta D.

, p. 646 - 657 (2007/10/02)

Alkylation of various β-ketoesters IIIa-d with bis(p-methoxycarbonylphenyl)bromomethane (II) and bis(p-chlorophenyl)bromomethane (VI) followed by cleavage of ethoxycarbonyl group or hydrolysis and esterification gave methoxycarbonylphenyl and chlorophenyl analogues of ar-juvabione, respectively.Condensation of bis(p-methoxycarbonylphenyl)methanol (IX) with isovaleryl and trichloroacetyl chloride gave isovalerate X and trichloroacetate XI, respectively, while the condensation of bis(p-chlorophenyl)methanol (XII) with isovaleryl chloride and citronellyl bromide yieldedisovalerate XIII and citronellyl ether XIV, respectively.The methoxycarbonylation of aryl-alkyl ketones XVa-d with oxalyl chloride and treatment with methanol furnished various ar-juvabione analogues XVIa-d.The compounds Vb, Vc, Vd, XVIb, and XVIc showed high activity against Dysdercus koenigii at 1μg concentration.
