1313271-99-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1313271-99-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,1,3,2,7 and 1 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1313271-99:
(9*1)+(8*3)+(7*1)+(6*3)+(5*2)+(4*7)+(3*1)+(2*9)+(1*9)=126
126 % 10 = 6
So 1313271-99-6 is a valid CAS Registry Number.

Rh2(S-PTAD)4-catalyzed asymmetric cyclopropenation of aryl alkynes
Briones, John F.,Davies, Huw M.L.
experimental part, p. 4313 - 4317 (2011/07/29)
Rh2(S-PTAD)4 is an effective catalyst for the asymmetric cyclopropenation of aryl alkynes using a siloxyvinyldiazoacetate as the carbenoid precursor. Upon deprotection of the silyl protecting group, highly enantioenriched cyclopropen
