Check Digit Verification of cas no

The CAS Registry Mumber 74089-99-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,0,8 and 9 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 74089-99:
(7*7)+(6*4)+(5*0)+(4*8)+(3*9)+(2*9)+(1*9)=159
159 % 10 = 9
So 74089-99-9 is a valid CAS Registry Number.

REACTION DE METATHESE DES OLEFINES INDUITE PHOTOCHIMIQUEMENT EN PRESENCE D'UN COMPLEXE DE METAL DE TRANSITION. VI. EXISTENCE PROBABLE D'UN METALLODICHLOROCARBENE PRIMAIRE

Garnier, F.,Krausz, P.,Rudler, H.

, p. 77 - 83 (1980)

Photochemically induced metathesis of RCH=CHR' olefins with W(CO)6 and CCl4 gives RCH=CCl2 and R'CH=CCl2.W(CO)6 in CCl4 reacts under illumination with cyclic enol ethers to give products resulting from the insertion of metalladichlorocarbene moieties into the carbon-carbon double bond.A mechanism for the formation of these compounds is outlined.
