97939-10-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 97939-10-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,7,9,3 and 9 respectively; the second part has 2 digits, 1 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 97939-10:
(7*9)+(6*7)+(5*9)+(4*3)+(3*9)+(2*1)+(1*0)=191
191 % 10 = 1
So 97939-10-1 is a valid CAS Registry Number.

Smaardijk, Ab. A.,Noorda, Simon,Bolhuis, Fre van,Wynberg, Hans
, p. 493 - 496 (1985)
The absolute configuration and CD spectra of a series of chiral α-hydroxyphosphonates and phosphoric acids have been determinated.The hydroxyphosphonates were prepared via a quinine catalyzed 1,2-addition reaction of phosphite to aldehyde.
