Check Digit Verification of cas no
The CAS Registry Mumber 75-12-7 includes 5 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 2 digits, 7 and 5 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 75-12:
(4*7)+(3*5)+(2*1)+(1*2)=47
47 % 10 = 7
So 75-12-7 is a valid CAS Registry Number.

Isomerization of matrix-isolated formamide: IR-spectroscopic detection of formimidic acid
Maier, Guenther,Endres, Joerg
, p. 1061 - 1063 (2007/10/03)
Ultraviolet irradiation of matrix-isolated formamide (1) in solid argon with light of wavelength 248 nm leads to the formation of formimidic acid (2). Comparison of the experimental IR spectrum of the photoproduct with the calculated IR spectrum of 2 shows clearly that two rotamers 2a and 2b are formed.
