Check Digit Verification of cas no

The CAS Registry Mumber 128176-45-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,1,7 and 6 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 128176-45:
(8*1)+(7*2)+(6*8)+(5*1)+(4*7)+(3*6)+(2*4)+(1*5)=134
134 % 10 = 4
So 128176-45-4 is a valid CAS Registry Number.

The effect of propargyl oxygen substituents in the carbene-chromium/alkyne cycloaddition

Semmelhack,Jeong,Lee

, p. 609 - 610 (1990)

The usual reaction of alkynes with arylcarbene chromium complexes is deflected by the presence of propargylic alkoxy groups, especially in the case of the 2,5-dimethoxyphenyl carbene ligand; indenes and furans become significant products.
