30771-70-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 30771-70-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,0,7,7 and 1 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 30771-70:
(7*3)+(6*0)+(5*7)+(4*7)+(3*1)+(2*7)+(1*0)=101
101 % 10 = 1
So 30771-70-1 is a valid CAS Registry Number.

Organic Synthesis with sulfones. XLI. Nucleophilic substitution of allylic sulfones
Julia, Marc,Nel, Maurice,Uguen, Daniel
, p. 487 - 492 (2007/10/02)
The sulfonyl group in allylic sulfones can be displaced by a variety of nucleophiles.The reaction is particularly easy with tertiary sulfones, i.e. bearing no hydrogen atoms at the α-position.Lewis acids catalyse the displacement reaction.
