Check Digit Verification of cas no
The CAS Registry Mumber 213270-44-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,3,2,7 and 0 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 213270-44:
(8*2)+(7*1)+(6*3)+(5*2)+(4*7)+(3*0)+(2*4)+(1*4)=91
91 % 10 = 1
So 213270-44-1 is a valid CAS Registry Number.

Practical access to 2-alkylsuccinates through asymmetric catalytic hydrogenation of Stobbe-derived itaconates
Burk, Mark J.,Bienewald, Frank,Harris, Michael,Zanotti-Gerosa, Antonio
, p. 1931 - 1933 (2007/10/03)
Enantiomerically pure 2-alkylsuccinates are obtained on a 500-g scale after hydrogenation with the cationic rhodium complexes with tetraalkyl-substituted 1,2-bis(phospholanyl)ethane or -benzene ligands [R'-DuPHOS; Eq. (a)]. The catalysts allow smooth hydr
