Check Digit Verification of cas no
The CAS Registry Mumber 1610-33-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,6,1 and 0 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1610-33:
(6*1)+(5*6)+(4*1)+(3*0)+(2*3)+(1*3)=49
49 % 10 = 9
So 1610-33-9 is a valid CAS Registry Number.

Paragraph 0038; 0039; 0043, (2013/04/25)
The present invention is directed to a new method for esterification of P-O components. More specifically, the present invention relates to a new method for esterification of P-O components containing at least one P-O-H functional group, whereby the P-O-H functional group(s) is converted into P-O-R functional group(s). The method according to the invention may find particular use in the manufacture of diesters of phosphorous acid.
