183952-40-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 183952-40-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,3,9,5 and 2 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 183952-40:
(8*1)+(7*8)+(6*3)+(5*9)+(4*5)+(3*2)+(2*4)+(1*0)=161
161 % 10 = 1
So 183952-40-1 is a valid CAS Registry Number.

Chelidonic acid as precursor for 2,5-desoxy-c-glycosides
Schmidt, Boris
, p. 179 - 182 (2007/10/03)
Diethyl chelidonate (1) was converted by 5 convenient steps into the 2,4,6-trifunctionalized tetrahydropyran (6), which is a key intermediate for natural products and peptide turn mimetics. The important all syn- configuration was achieved by catalytic hydrogenation.
