Check Digit Verification of cas no

The CAS Registry Mumber 70083-75-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,0,0,8 and 3 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 70083-75:
(7*7)+(6*0)+(5*0)+(4*8)+(3*3)+(2*7)+(1*5)=109
109 % 10 = 9
So 70083-75-9 is a valid CAS Registry Number.

Metallorganische Lewis-Saeuren. XXXVII. Kationische Pentacarbonyl(phosphan)rhenium-komplexe und deren Reactionen mit Nucleophilen

Steil, Peter,Sacher, Wolfgang,Fritz, Peter M.,Beck, Wolfgang

, p. 363 - 374 (1989)

The raections of pentacarbonyltetrafluoroboratorhenium, (OC)5ReFBF3, with PH3, PPh3, PPh2H, and chlorphosphanes lead to cationic complexes +BF4- (1).Nucleophiles react with the chlorphosphane ligands of 1 to give the ionic complexes +BF4- (R'=OH, OMe, OEt).Reaction of +BF4- with OH- yields the bridged 2+2BF4-, whereas with +BF4- and OH- the complex +BF4- is formed.The azide ion is added to a cis-carbonyl ligand of +BF4- to form the neutral isocyanato complex (OC)4(ClPh2P)ReNCO.The hydroxycarbonyl complexes cis-(OC)4Re(PPh2R)(COOH) are obtained from the reaction of +BF4- (R=Ph, H) with hydroxide.The reactions of + with M(CO)5- (L=PPh3, P(OMe)3, CN-tBu; M=Mn, Re) give the nonacarbonyl dimetal compounds L(OC)4Re-M(CO)5.
