134256-79-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 134256-79-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,4,2,5 and 6 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 134256-79:
(8*1)+(7*3)+(6*4)+(5*2)+(4*5)+(3*6)+(2*7)+(1*9)=124
124 % 10 = 4
So 134256-79-4 is a valid CAS Registry Number.

Tin Effects in the Hydroboration of Hindered Olefins
Akers, James A.,Bryson, Thomas A.
, p. 3453 - 3458 (2007/10/02)
Intermolecular hydroboration of tetrasubstituted olefins is enhanced by allylic tin substituents.Intramolecular hydroboration using hindered allylic tin substrates is found to be inefficient presumably due to the steric bulk of the trialkylstannane group.
