Check Digit Verification of cas no

The CAS Registry Mumber 119862-68-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,9,8,6 and 2 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 119862-68:
(8*1)+(7*1)+(6*9)+(5*8)+(4*6)+(3*2)+(2*6)+(1*8)=159
159 % 10 = 9
So 119862-68-9 is a valid CAS Registry Number.

Cocyclisation des complexes biscarbeniques avec le diphenylacetylene: synthese de derives de bisnaphtols et de bisindenes

Huy, N. Hoa Tran,Lefloch, P.

, p. 303 - 312 (1988)

The bis-carbene complexes p-2(C6H4) and p,p'-2(C6H4)2 (M=Cr, W) react with diphenylacetylene in two different ways: (a) benzannulation leading to naphthol derivatives (M=Cr) and (b) cycloaddition giving indene derivatives.The preparation and spectroscopic data of these compounds are reported and discussed.
