195512-73-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 195512-73-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,5,5,1 and 2 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 195512-73:
(8*1)+(7*9)+(6*5)+(5*5)+(4*1)+(3*2)+(2*7)+(1*3)=153
153 % 10 = 3
So 195512-73-3 is a valid CAS Registry Number.

(2S,3R)-2-Benzyloxy-3,4-epoxybutan-1-ol; A Versatile Synthetic Building Block Formally Derived From (u)-Tartaric acid
Adam, Geo,Seebach, Dieter
, p. 373 - 375 (2007/10/02)
The title chiral C4-building block 1, a meso-tartaric acid synthon, is prepared from dimethyl (R,R)-O,O'-benzylidenetartrate on a multigram scale.The key step is a tosylation-reduction sequence which leads to the diol 5.
