nuances and a hint of cinnamon spice.
Check Digit Verification of cas no
The CAS Registry Mumber 4440-65-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,4,4 and 0 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 4440-65:
(6*4)+(5*4)+(4*4)+(3*0)+(2*6)+(1*5)=77
77 % 10 = 7
So 4440-65-7 is a valid CAS Registry Number.

Selective reduction of carboxylic acids to aldehydes catalyzed by B(C 6F5)3
Bezier, David,Park, Sehoon,Brookhart, Maurice
supporting information, p. 496 - 499 (2013/03/29)
B(C6F5)3 efficiently catalyzes hydrosilylation of aliphatic and aromatic carboxylic acids to produce disilyl acetals under mild conditions. Catalyst loadings can be as low as 0.05 mol %, and bulky tertiary silanes are favored to give selectively the acetals. Acidic workup of the disilyl acetals results in the formation of aldehydes in good to excellent yields.
