109706-88-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 109706-88-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,9,7,0 and 6 respectively; the second part has 2 digits, 8 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 109706-88:
(8*1)+(7*0)+(6*9)+(5*7)+(4*0)+(3*6)+(2*8)+(1*8)=139
139 % 10 = 9
So 109706-88-9 is a valid CAS Registry Number.

Aspects of the Chemistry of 6-Diazopenicillanate-S-Oxide and S,S-Dioxide
Hanlon, Barbara,John, D.Ivor
, p. 2207 - 2212 (2007/10/02)
Procedures are developed for the preparation of 6-diazopenicillanate S-oxides and S,S-dioxides from the corresponding 6-phenylacetamidopenicillanates by N-nitrosation and thermal decomposition of the intermediate N-nitroso amides.The chemistry of these 6-
