Check Digit Verification of cas no

The CAS Registry Mumber 1023531-31-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,2,3,5,3 and 1 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1023531-31:
(9*1)+(8*0)+(7*2)+(6*3)+(5*5)+(4*3)+(3*1)+(2*3)+(1*1)=88
88 % 10 = 8
So 1023531-31-8 is a valid CAS Registry Number.

Well-defined air-stable palladium HASPO complexes for efficient Kumada-Corriu cross-couplings of (Hetero)aryl or alkenyl tosylates

Ackermann, Lutz,Kapdi, Anant R.,Fenner, Sabine,Kornhaab, Christoph,Schulzke, Carola

supporting information; experimental part, p. 2965 - 2971 (2011/05/05)

Palladium complexes of representative heteroatom-substituted secondary phosphine oxide (HASPO) preligands were synthesized and fully characterized, including X-ray crystal structure analysis. Importantly, these well-defined complexes served as highly efficient catalysts for Kumada-Corriu cross-coupling reactions of aryl, alkenyl, and even heteroaryl tosylates. Particularly, an air-stable catalyst derived from inexpensive PinP(O)H displayed a remarkably high catalytic efficacy, which resulted in cross-couplings at low catalyst loadings under exceedingly mild reaction conditions with ample scope.
