219532-16-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 219532-16-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,9,5,3 and 2 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 219532-16:
(8*2)+(7*1)+(6*9)+(5*5)+(4*3)+(3*2)+(2*1)+(1*6)=128
128 % 10 = 8
So 219532-16-8 is a valid CAS Registry Number.

, p. 2399 - 2404 (2007/10/03)
The first total synthesis of enantiomerically enriched (+)-and (-)-corydalisol (1) has been performed by addition of lithiated optically pure 1,3-dithiane 3b to hydrastinine chloride (2a), followed by desulfurization, separation of diastereomers and reduc
