138611-62-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 138611-62-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,6,1 and 1 respectively; the second part has 2 digits, 6 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 138611-62:
(8*1)+(7*3)+(6*8)+(5*6)+(4*1)+(3*1)+(2*6)+(1*2)=128
128 % 10 = 8
So 138611-62-8 is a valid CAS Registry Number.

79Br NQR SPECTRA AND ELECTRONIC EFFECTS IN BROMO-SUBSTITUTED ORGANIC CARBONYL COMPOUNDS
Shchepin, V. V.,Efremov, D. I.,Petukhov, S. A.,Russkikh, N. Yu.
, p. 105 - 107 (2007/10/03)
79Br NQR spectra of the carbonyl compounds R1R2CBrC(O)X (R1, R2= H, Alk, Hlg; X = H, Alk, Ar, Hlg, functional groups) were studied.The average 79Br NQR frequency is very sensitive to electronic properties of the
