Check Digit Verification of cas no

The CAS Registry Mumber 1257313-78-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,7,3,1 and 3 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1257313-78:
(9*1)+(8*2)+(7*5)+(6*7)+(5*3)+(4*1)+(3*3)+(2*7)+(1*8)=152
152 % 10 = 2
So 1257313-78-2 is a valid CAS Registry Number.

Application of Silica-Supported Alkylating Reagents in a One-Pot, Sequential Protocol to Diverse Benzoxathiazepine 1,1-Dioxides

Faisal, Saqib,Maity, Pradip K.,Zang, Qin,Samarakoon, Thiwanka B.,Sourk, Robert L.,Hanson, Paul R.

, p. 387 - 393 (2016)

Applications of silica-ROMP reagents in a one-pot, sequential protocol have been developed for the synthesis of a variety of diverse benzoxathiazepine 1,1-dioxides. This protocol includes sulfonylation, intramolecular SNAr, alkylation with silica-supported oligomeric benzyl (Si-OBPn) and triazole (Si-OTPn) phosphates, and intermolecular SNAr addition with a number of secondary amines in one-pot to afford a variety of unique benzoxathiazepine 1,1-dioxides sultams in good to excellent yields.
