345659-76-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 345659-76-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,4,5,6,5 and 9 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 345659-76:
(8*3)+(7*4)+(6*5)+(5*6)+(4*5)+(3*9)+(2*7)+(1*6)=179
179 % 10 = 9
So 345659-76-9 is a valid CAS Registry Number.

Allenes from ynals
Tius, Marcus A.,Pal, Subrata K.
, p. 2605 - 2608 (2007/10/03)
Hydrosilylation of ynals with triethylsilane is catalyzed by RhCl(PPh3)3 and leads to α-triethylsilyl enals. Addition of aryl Grignard reagents takes place to give secondary allylic alcohols which are easily converted to 1,3-disubstituted allenes.
