99656-27-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 99656-27-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,9,6,5 and 6 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 99656-27:
(7*9)+(6*9)+(5*6)+(4*5)+(3*6)+(2*2)+(1*7)=196
196 % 10 = 6
So 99656-27-6 is a valid CAS Registry Number.

The cycloaddition reactions of bridgehead enones derived in situ from ketones 8,9, and 10 with various dienes at 0 deg C afford good yields of adducts.Even 1,1,3-trisubstituted dienes work well.The exclusive exo stereochemistry can be rationalized in term
