173547-35-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 173547-35-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,3,5,4 and 7 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 173547-35:
(8*1)+(7*7)+(6*3)+(5*5)+(4*4)+(3*7)+(2*3)+(1*5)=148
148 % 10 = 8
So 173547-35-8 is a valid CAS Registry Number.

Clemmensen Reduction. XI. Fragmentation Reactions of Some 3-Acetylcycloalkanones
Bailey, Karen E.,Davis, Brian R.
, p. 1827 - 1834 (2007/10/03)
Clemmensen reduction of a series of 3-acetylcycloalkanones yields, as the major product, an acyclic unsaturated ketone, the product of fragmentation.Some normal carbonyl-methylene reduction also occurs.A mechanistic rationale for the fragmentation is advanced.
