Check Digit Verification of cas no

The CAS Registry Mumber 83917-80-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,3,9,1 and 7 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 83917-80:
(7*8)+(6*3)+(5*9)+(4*1)+(3*7)+(2*8)+(1*0)=160
160 % 10 = 0
So 83917-80-0 is a valid CAS Registry Number.

Rhodium Carbonyl Catalyzed Carbonylation of Unsaturated Compounds. 2. Synthesis of 5-Alkoxy-2(5H)-furanones by the Carbonylation of Acetylenes in Alcohol

Mise, Takaya,Hong, Pangbu,Yamazaki, Hiroshi

, p. 238 - 242 (1983)

The carbonylation of diphenylacetylene (1a) in ethanol in the presence of Rh4(CO)12/Na2CO3 as a catalyst gave 5-ethoxy-3,4-diphenyl-2(5H)-furanone (3b) in a 72percent yield, together with 3-(ethoxycarbonyl)-2-phenylindanone (11percent) and diethyl 2,3-dip
