Check Digit Verification of cas no

The CAS Registry Mumber 136909-03-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,6,9,0 and 9 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 136909-03:
(8*1)+(7*3)+(6*6)+(5*9)+(4*0)+(3*9)+(2*0)+(1*3)=140
140 % 10 = 0
So 136909-03-0 is a valid CAS Registry Number.

SYNTHESIS OF ACID-LABILE GEMINAL BIS- AND TRIPHOSPHONIC ACIDS

Gross, H.,Keitel, I.,Costisella, B.

, p. 177 - 181 (2007/10/02)

Sodium salts (7,8 respectively) of the unsaturated bisphosphonic acids 5 (2,6-di-tert-butyl-7,7-bis(phosphono)-1,4-benzoquinone-4-methide) and the trisphosphonic acid 6 (4-hydroxy-3,5-di-tert-butylphenylmethane tris(phosphonic acid), were prepared by buffered hydrolysis of the corresponding trimethylsilyl esters.The structures of 7 and 8 were determined by 13C and 31P NMR analysis.Compound 8 is the first wellestablished example of a gem trisphosphnic acid salt. Key words: 7-phosphono-quinonemethide salts; arylmethane trisphosphonate; bromotrimethylsilane; silyldealkylation; 13C, 23Na, 31P NMR data.
