Check Digit Verification of cas no
The CAS Registry Mumber 227312-04-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,7,3,1 and 2 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 227312-04:
(8*2)+(7*2)+(6*7)+(5*3)+(4*1)+(3*2)+(2*0)+(1*4)=101
101 % 10 = 1
So 227312-04-1 is a valid CAS Registry Number.

A synthetic approach to methyl thieno[2,3-d][1,2,3]thiadiazole carboxylates via diazotation
Stanetty, Peter,Mihovilovic, Marko D.
, p. 573 - 580 (1999)
A route to methyl thieno[2,3-d][1,2,3]thiadiazole carboxylates 3 as highly potent inducers of systemic acquired resistance (SAR) is reported. The construction of the appropriately substituted thiophene precursors is elaborated. Cyclization towards the thi
