Check Digit Verification of cas no

The CAS Registry Mumber 1613416-90-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,1,3,4,1 and 6 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1613416-90:
(9*1)+(8*6)+(7*1)+(6*3)+(5*4)+(4*1)+(3*6)+(2*9)+(1*0)=142
142 % 10 = 2
So 1613416-90-2 is a valid CAS Registry Number.

Dihydrothiophenes containing quaternary stereogenic centres by sequential stereospecific rearrangements and ring-closing metathesis

Mingat, Ga?lle,McDouall, Joseph J. W.,Clayden, Jonathan

, p. 6754 - 6757 (2014/06/23)

Stereospecific [3,3]-sigmatropic rearrangement of O-substituted thiocarbamate derivatives of enantiopure allylic alcohols provides allylic thiocarbamates as single enantiomers. Intramolecular arylation by rearrangement of their allyllithium derivatives provides allylic tertiary thiols. Allylation and ring-closing metathesis gives 2,5-dihydrothiophenes containing sulfur-bearing quaternary centres. This journal is the Partner Organisations 2014.
