326603-45-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 326603-45-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,2,6,6,0 and 3 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 326603-45:
(8*3)+(7*2)+(6*6)+(5*6)+(4*0)+(3*3)+(2*4)+(1*5)=126
126 % 10 = 6
So 326603-45-6 is a valid CAS Registry Number.

, p. 273 - 277 (2008/12/22)
Unit A of cryptophycin 1 is a δ-hydroxy acid with four stereogenic centres. Our unit A synthesis introduces the first two stereogenic centres by a catalytic, asymmetric dihydroxylation, whereas the remaining two stereogenic centres are established by dias
