1263771-59-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1263771-59-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,6,3,7,7 and 1 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1263771-59:
(9*1)+(8*2)+(7*6)+(6*3)+(5*7)+(4*7)+(3*1)+(2*5)+(1*9)=170
170 % 10 = 0
So 1263771-59-0 is a valid CAS Registry Number.

, p. 2743 - 2746 (2010)
1-Silaindenes are prepared starting from (2-vinylphenyl)hydrosilanes and alkynes through a ruthenium-catalyzed hydrosilylation-ring-closing-metathesis sequence. The method is successfully applied to the synthesis of molecules containing multiple silaindene units.
