81112-99-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 81112-99-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,1,1 and 2 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 81112-99:
(7*8)+(6*1)+(5*1)+(4*1)+(3*2)+(2*9)+(1*9)=104
104 % 10 = 4
So 81112-99-4 is a valid CAS Registry Number.

Utimoto, Kiitiro,Miwa, Hiroshi,Nozaki, Hitosi
, p. 4277 - 4278 (2007/10/02)
Pyrrole derivatives are prepared in high yields by the catalytic action of a Pd(II) salt on 1-amino-3-alkyn-2-ols which are obtained from conjugate ynones.
