216577-48-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 216577-48-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,6,5,7 and 7 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 216577-48:
(8*2)+(7*1)+(6*6)+(5*5)+(4*7)+(3*7)+(2*4)+(1*8)=149
149 % 10 = 9
So 216577-48-9 is a valid CAS Registry Number.

, p. 3143 - 3144 (2007/10/03)
Starting from (R)-carvone, the synthesis of chiral, functionalised C-aromatic-B-seco-taxanes and an extension to the synthesis of a B-seco-20-nortaxane derivative have been described.
