Check Digit Verification of cas no

The CAS Registry Mumber 1218992-56-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,1,8,9,9 and 2 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1218992-56:
(9*1)+(8*2)+(7*1)+(6*8)+(5*9)+(4*9)+(3*2)+(2*5)+(1*6)=183
183 % 10 = 3
So 1218992-56-3 is a valid CAS Registry Number.

Synthesis of a monophosphoryl derivative of Escherichia coli lipid A and Its efficient coupling to a tumor-associated carbohydrate antigen

Tang, Shouchu,Wang, Qianli,Guo, Zhongwu

experimental part, p. 1319 - 1325 (2010/06/14)

Monophosphoryl lipid A is a safe and potent immunostimulant and vaccine adjuvant, which is potentially useful for the development of effective carbohydrate-based conjugate vaccines. This paper presents a convergent and efficient synthesis of a monophosphoryl derivative of E. coli lipid A that has an alkyne functionality at the reducing end, which is suitable for coupling with various molecules. The coupling of this derivative to an N-modified analogue of tumor-associated antigen GM3 through click chemistry is also presented.
