Check Digit Verification of cas no

The CAS Registry Mumber 171504-39-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,1,5,0 and 4 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 171504-39:
(8*1)+(7*7)+(6*1)+(5*5)+(4*0)+(3*4)+(2*3)+(1*9)=115
115 % 10 = 5
So 171504-39-5 is a valid CAS Registry Number.

Preparation of olefins and acetylenes via reductive elimination with Sml2-HMPA

Ihara, Masataka,Suzuki, Shuichi,Taniguchi, Takahiko,Tokunaga, Yuji,Fukumoto, Keiichiro

, p. 9873 - 9890 (1995)

Reaction of β-hydroxy or acetoxy sulfones with Sml2 in the presence of HMPA caused effectively reductive elimination to provide olefins. Treatment of enol phosphates, readily synthesized from β-hydroxy sulfones via keto sulfones, under the same conditions efficiently produced mono- and disubstituted acetylenes.
