Check Digit Verification of cas no

The CAS Registry Mumber 1352281-08-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,5,2,2,8 and 1 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1352281-08:
(9*1)+(8*3)+(7*5)+(6*2)+(5*2)+(4*8)+(3*1)+(2*0)+(1*8)=133
133 % 10 = 3
So 1352281-08-3 is a valid CAS Registry Number.

Three types of products by carbon nucleophiles toward methoxyphenylacetylenic sulfones

Cheng, Chia-Yi,Isobe, Minoru

, p. 9957 - 9965 (2012/02/06)

Methoxy-arylacetylenic sulfones were examined to react with various carbanion nucleophiles to result in the three types of products; thus, (i) nucleophiles (MeLi·LiBr, Vinyl MgBr, LiCH2CN) showed the α-addition, however, (ii) Li-CC-TMS afforded β-addition (conjugate addition) products. The (iii) displacement reaction through α-addition/ isomerization/trans-elimination was enhanced by the presence of ortho-methoxy group at high temperature. The heteroatom nucleophiles (nitrogen, oxygen or sulfur atom) in a protic solvent provided only conjugate addition products as reported.
