1609178-43-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1609178-43-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,0,9,1,7 and 8 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1609178-43:
(9*1)+(8*6)+(7*0)+(6*9)+(5*1)+(4*7)+(3*8)+(2*4)+(1*3)=179
179 % 10 = 9
So 1609178-43-9 is a valid CAS Registry Number.

A cyclopropanol-based approach to synthesis of Unit A of the cryptophycins
Shklyaruck, Denis G.
, p. 644 - 649 (2014/05/20)
A new asymmetric synthesis of Unit A of the cryptophycins has been carried out yielding 13% of the target product over 14 steps. The key steps of the synthesis were diastereoselective hydroboration-oxidation reactions performed on the alkenyl moiety of a
