Check Digit Verification of cas no

The CAS Registry Mumber 193750-57-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,3,7,5 and 0 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 193750-57:
(8*1)+(7*9)+(6*3)+(5*7)+(4*5)+(3*0)+(2*5)+(1*7)=161
161 % 10 = 1
So 193750-57-1 is a valid CAS Registry Number.

Cleavage Reactions of some Phenyltin Compounds with Iodine Halides, -Pseudohalides and -Carboxylates

Srivastava,Singh,Tangri,Sinha,Bajpai

, p. 443 - 445 (2007/10/03)

Cleavage reactions of iodinehalides, -pseudohalides IX (X = Cl, Br, NCO, NCS, N3 and CN) with Ph3SnCp yield triphenyltinhalides, -pseudohalides (Ph3SnX) indicating cleavage of Cp-Sn bond in preference to Ph-Sn bond, and cleavage reactions of iodine carboxylates IX′ (X′ = CH3OCO, C5H5OCO, C6H5CH2OCO, o-NH2C6H4OCO, o-CIC6H4OCO, p-NO2C6H4OCO, p-NH2C6H4OCO, C6H5CH =CHOCO) (in situ) with Ph3SnCl give hitherto unknown diphenylchlorotin carboxylates (Ph2SnX′Cl) indicating cleavage of Ph-Sn bond in preference to Cl-Sn bond. On the basis of the results, it is predicated that these diphenylchlorotin carboxylates possess bridging carboxylate groups (inter-molecularly chelated structure) in the solid state, whereas in solution they contain chelated carboxylate groups (intra-molecularly chelated structures).
