211570-33-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 211570-33-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,1,5,7 and 0 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 211570-33:
(8*2)+(7*1)+(6*1)+(5*5)+(4*7)+(3*0)+(2*3)+(1*3)=91
91 % 10 = 1
So 211570-33-1 is a valid CAS Registry Number.

Kang, Sung Ho,Kim, Joon Seop
, p. 1353 - 1354 (2007/10/03)
A divergent synthetic route to (+)-castanospermine 1 and (+)-6-epicastanospermine 2 has been developed via phenylselenoamidation of trichloroacetimidate derived from allylic alcohol 7, and dihydroxylations of trans-olefins 14 and 18 to dispose the three c
