663604-98-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 663604-98-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,6,3,6,0 and 4 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 663604-98:
(8*6)+(7*6)+(6*3)+(5*6)+(4*0)+(3*4)+(2*9)+(1*8)=176
176 % 10 = 6
So 663604-98-6 is a valid CAS Registry Number.

Synthesis of N-heterocyclic diols by diastereoselective pinacol coupling reactions
Handa, Sandeep,Kachala, Manpreet S.,Lowe, Sarah R.
, p. 253 - 256 (2007/10/03)
A series of 5-8 membered N-heterocyclic diols have been prepared from acyclic dicarbonyls via diastereoselective pinacol reactions whereby cis- or trans-diol stereoselectivity is controlled by the choice of low-valent metal reagent used.
