107905-20-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 107905-20-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,7,9,0 and 5 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 107905-20:
(8*1)+(7*0)+(6*7)+(5*9)+(4*0)+(3*5)+(2*2)+(1*0)=114
114 % 10 = 4
So 107905-20-4 is a valid CAS Registry Number.

Z ISOMERS OF PYRUVIC ACID AMIDE THIOSEMICARBAZONES
Poplavskaya, I. A.,Khalilova, S. F.
, p. 657 - 658 (2007/10/02)
Treatment of the amphi isomers of acetylformamidoxime thiosemicarbazones with nitrous acid does not effect the thiosemicarbazone residue and leads to previously unknown Z isomers of pyruvic acid amide thiosemicarbazones.
