553642-23-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 553642-23-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,5,3,6,4 and 2 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 553642-23:
(8*5)+(7*5)+(6*3)+(5*6)+(4*4)+(3*2)+(2*2)+(1*3)=152
152 % 10 = 2
So 553642-23-2 is a valid CAS Registry Number.

Intermolecular C-H activation at benzylic positions: Synthesis of (+)-imperanene and (-)-α-conidendrin
Davies, Huw M. L.,Jin, Qihui
, p. 941 - 949 (2007/10/03)
An efficient C-H activation of primary benzylic positions by means of rhodium carbenoid induced C-H insertions is described. This key step was used in concise syntheses of (+)-imperanene and (-)-α-conidendrin.
