Check Digit Verification of cas no

The CAS Registry Mumber 1427214-08-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,2,7,2,1 and 4 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1427214-08:
(9*1)+(8*4)+(7*2)+(6*7)+(5*2)+(4*1)+(3*4)+(2*0)+(1*8)=131
131 % 10 = 1
So 1427214-08-1 is a valid CAS Registry Number.

Novel mixed-heteroatom macrocycles via templating: A new protocol

Sabah, Karem J.,Hashim, Rauzah

, p. 1534 - 1537 (2013)

A series of novel thiadiaza and triaza crown ether attached galactose- and glucose-based glycolipids is synthesized, applying a new strategy. The key step is the formation of α-chloroacetamido precursors (14 and 21) from selectively protected bis(cyanomethyl)-glycolipids (13 and 19) in two steps. The cyclization reaction furnishes good yields in relatively short times in aqueous ethanol or acetonitrile. To generalize this method, macrocycles 3 and 25 are reported as well. Attempts to use the traditional synthetic approaches for cyclization failed to provide reasonable yields.
