173005-99-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 173005-99-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,3,0,0 and 5 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 173005-99:
(8*1)+(7*7)+(6*3)+(5*0)+(4*0)+(3*5)+(2*9)+(1*9)=117
117 % 10 = 7
So 173005-99-7 is a valid CAS Registry Number.

Alkylations of chiral, phosphoryl- and thiophosphoryl-stabilized carbanions
Denmark, Scott E.,Chen, Chien-Tien
, p. 11879 - 11897 (2007/10/03)
A general method for the preparation of enantiomerically enriched phosphonic acids and phosphonates with three different α-substitution patterns (aryl, alkyl, and alkoxy) has been developed. Anions derived from enantiomerically enriched thiophosphonamidat
