Check Digit Verification of cas no

The CAS Registry Mumber 131897-45-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,1,8,9 and 7 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 131897-45:
(8*1)+(7*3)+(6*1)+(5*8)+(4*9)+(3*7)+(2*4)+(1*5)=145
145 % 10 = 5
So 131897-45-5 is a valid CAS Registry Number.

REACTION OF Δ3-PYRROLINES WITH DIMETHYL ACETYLENEDICARBOXYLATE. A NOVEL PYRROLE FORMING REARRANGEMENT

Grigg, Ronald,Gunaratne, H.Q. Nimal,Kemp, James

, p. 99 - 102 (1984)

Reaction of arylidene imines of methyl phenylglycinate with 2 moles of dimethyl acetylenedicarboxylate (ADE) leads, via an intermediate Δ3-pyrroline, to loss of the original methyl phenylglycinate moiety and formation of 2-aryl-3,4,5-tricarbo methoxypyrroles.

X=Y-ZH compounds as potential 1,3-dipoles. Part 30. Cycloaddition of arylidene imines of α-amino esters to acetylenic dipolarophiles and pyrrole forming rearrangements

Grigg, Ronald,Gunaratne, H. Q. Nimal,Kemp, James

, p. 6467 - 6482 (2007/10/02)

Arylidene imines of α-amino esters undergo cycloaddition to ethyl phenylpropiolate, methyl propiolate and dimethyl acetylenedicarboxylate (ADE) on heating in toluene (110°C)or o-xylene (135- 145°C). The reactions proceed via stereospecific azomethine ylid
