1263820-24-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1263820-24-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,6,3,8,2 and 0 respectively; the second part has 2 digits, 2 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1263820-24:
(9*1)+(8*2)+(7*6)+(6*3)+(5*8)+(4*2)+(3*0)+(2*2)+(1*4)=141
141 % 10 = 1
So 1263820-24-1 is a valid CAS Registry Number.

Endo-selective enyne ring-closing metathesis promoted by stereogenic-at-W mono-pyrrolide complexes
Zhao, Yu,Hoveyda, Amir H.,Schrock, Richard R.
, p. 784 - 787 (2011)
The utility of W-alkylidene complexes for enyne ring-closing metathesis is demonstrated in a direct comparison with Mo-based analogs. Tungsten complexes lead to less alkyne oligomerization and higher levels of endo-selectivity and enantioselectivity.
