Check Digit Verification of cas no

The CAS Registry Mumber 314082-75-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,1,4,0,8 and 2 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 314082-75:
(8*3)+(7*1)+(6*4)+(5*0)+(4*8)+(3*2)+(2*7)+(1*5)=112
112 % 10 = 2
So 314082-75-2 is a valid CAS Registry Number.

Reversible C ? N migration of the ethoxycarbonyl group in the reactions of pyridinium and isoquinolinium ylides derived from malonic ester with isocyanates

Gololobov, Yuri G.,Dovgan, Olga V.,Golding, Igor R.,Petrovskii, Pavel V.,Garbuzova, Irina A.

, p. 36 - 45 (2002)

Pyridinium and isoquinolinium ylides (7 and 12) derived from malonic ester react in an unusual manner with isocyanates giving the new pyridinium ylide (9) and the new isoquinolinium ylide (14). C → N Migration of the COOEt group takes place at room temperature, but, at an elevated temperature, reverse N → C migration of the COOEt group proceeds and ylides 9 and 14 are reconverted into the starting ylides 7 and 12, respectively.
