247905-02-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 247905-02-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,4,7,9,0 and 5 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 247905-02:
(8*2)+(7*4)+(6*7)+(5*9)+(4*0)+(3*5)+(2*0)+(1*2)=148
148 % 10 = 8
So 247905-02-8 is a valid CAS Registry Number.

Chiral palladium complex-catalyzed synthesis of optically active vinylchroman
Mizuguchi,Achiwa
, p. 1209 - 1211 (2007/10/03)
Optically active vinylchroman (1) was synthesized from a corresponding allyl carbonate (2) by catalytic and asymmetric allylic substitution with palladium complexes of chiral bisphosphine ligands. The reactivity and selectivity of the various chiral bisph
