1337993-69-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1337993-69-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,3,7,9,9 and 3 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1337993-69:
(9*1)+(8*3)+(7*3)+(6*7)+(5*9)+(4*9)+(3*3)+(2*6)+(1*9)=207
207 % 10 = 7
So 1337993-69-7 is a valid CAS Registry Number.

Synthesis and reactivity of alkyl-1,1,1-trisphosphonate esters
Smits, Jacqueline P.,Wiemer, David F.
, p. 8807 - 8813 (2011/12/04)
The α-trisphosphonic acid esters provide a unique spatial arrangement of three phosphonate groups and may represent an attractive motif for inhibitors of enzymes that utilize di- or triphosphate substrates. To advance studies of this unique functionality,
