Check Digit Verification of cas no

The CAS Registry Mumber 1225441-55-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,2,5,4,4 and 1 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1225441-55:
(9*1)+(8*2)+(7*2)+(6*5)+(5*4)+(4*4)+(3*1)+(2*5)+(1*5)=123
123 % 10 = 3
So 1225441-55-3 is a valid CAS Registry Number.

Divergent synthesis of lamellarin α 13-sulfate, 20-sulfate, and 13,20-disulfate

Fukuda, Tsutomu,Ohta, Takeshi,Saeki, Sho,Iwao, Masatomo

, p. 841 - 846 (2010)

A divergent synthesis of three sulfate derivatives of lamellarin α, namely, lamellarin α 13-sulfate (2), 20-sulfate (1), and 13,20-disulfate (4) has been achieved via a common intermediate (6) in which 13-OH and 20-OH of the lamellarin core are differentially protected by MOM and benzyl groups, respectively. Compound (6) in turn was prepared using sequential Suzuki-Miyaura coupling of 3,4-dihydroxypyrrole bistriflate (7) as a key reaction.
