641627-94-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 641627-94-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,4,1,6,2 and 7 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 641627-94:
(8*6)+(7*4)+(6*1)+(5*6)+(4*2)+(3*7)+(2*9)+(1*4)=163
163 % 10 = 3
So 641627-94-3 is a valid CAS Registry Number.

The Total Synthesis of (-)-Lemonomycin
Ashley, Eric R.,Cruz, Ernest G.,Stoltz, Brian M.
, p. 15000 - 15001 (2007/10/03)
The first total synthesis of the novel glycosylated tetrahydroisoquinoline antitumor antibiotic (?)-lemonomycin has been accomplished (15 steps from 9). The highly convergent synthesis relies on a key asymmetric dipolar cycloaddition to set the stereochem
