Check Digit Verification of cas no

The CAS Registry Mumber 1048681-66-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,4,8,6,8 and 1 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1048681-66:
(9*1)+(8*0)+(7*4)+(6*8)+(5*6)+(4*8)+(3*1)+(2*6)+(1*6)=168
168 % 10 = 8
So 1048681-66-8 is a valid CAS Registry Number.

Finding the proton in a key intermediate of anti-markovnikov alkyne hydration by a bifunctional catalyst

Grotjahn, Douglas B.,Kragulj, Elijah J.,Zeinalipour-Yazdi, Constantinos D.,Miranda-Soto, Valentin,Lev, Daniel A.,Cooksy, Andrew L.

supporting information; experimental part, p. 10860 - 10861 (2009/02/05)

The secondary structure of a bifunctional catalyst positions a crucial reactive proton in the final intermediate of anti-Markovnikov alkyne hydration to give an aldehyde. NMR coupling and isotopic labeling studies elucidate the location of this proton and its involvement in hydrogen bonding. Copyright
