Check Digit Verification of cas no

The CAS Registry Mumber 125722-48-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,5,7,2 and 2 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 125722-48:
(8*1)+(7*2)+(6*5)+(5*7)+(4*2)+(3*2)+(2*4)+(1*8)=117
117 % 10 = 7
So 125722-48-7 is a valid CAS Registry Number.

OPTICALLY ACTIVE SILYL ESTERS OF PHOSPHOROUS. II. STEREOCHEMISTRY OF REACTIONS WITH NUCLEOPHILES

Wozniak, Lucyna,Cypryk, Marek,Chojnowski, Julian

, p. 4403 - 4414 (2007/10/02)

We report the stereochemistry of reactions of various nucleophiles with optically active silyl esters of phosphorus of general formula: tBuPhP(X)OSiMePhNp X= -(1), Oxygen (2), Sulfur (3), Selenium (4).The list of nucleophiles includes O,S,N,C nucleophiles as well as halides.The nucleophilic attack is essentially directed towards silicon.The phosphinuos and phosphonic acid esters react with predominant retention of configuration at silicon atom, whereas the thiono and seleno crossover is explained in terms of possible interaction of the electrophilic part of the nucleophile with the oxyphosphoryl group or tricoordinate phosphorous.
