Check Digit Verification of cas no
The CAS Registry Mumber 13820-09-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,8,2 and 0 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 13820-09:
(7*1)+(6*3)+(5*8)+(4*2)+(3*0)+(2*0)+(1*9)=82
82 % 10 = 2
So 13820-09-2 is a valid CAS Registry Number.

A flexible Pinner preparation of orthoesters: The model case of trimethylorthobenzoate
Noe, Marco,Perosa, Alvise,Selva, Maurizio
, p. 2252 - 2260 (2013)
In the absence of additional solvents, a novel procedure was implemented for the synthesis of trimethylorthoesters through the Pinner reaction. At 5 °C, the reaction of both aliphatic and aromatic nitriles (RCN; R = Et, Bu, Ph) with a moderate excess of MeOH and gaseous HCl gave the corresponding imidate hydrochlorides [RC(NH)OR′·HCl] in excellent yields (>90%). At 25-65 °C, the methanolysis of alkyl imidate salts provided trimethylortho-propionate and valerate, while only traces of trimethylorthobenzoate (TMOB) were observed. However, the aromatic hydrochloride could be readily converted into the hydrogenphosphate salt [PhC(NH) OR′·H3PO4] which, in turn, underwent a selective (>80%) reaction with MeOH to produce TMOB in a 62% isolated yield. This allowed for an unprecedented Pinner-type synthesis of TMOB starting from benzonitrile, rather than from the highly toxic trichloromethylbenzene. Overall, remarkable improvements in safety and process intensification were achieved.
