Check Digit Verification of cas no

The CAS Registry Mumber 13399-20-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,3,9 and 9 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 13399-20:
(7*1)+(6*3)+(5*3)+(4*9)+(3*9)+(2*2)+(1*0)=107
107 % 10 = 7
So 13399-20-7 is a valid CAS Registry Number.

supporting information; experimental part, p. 76 - 78 (2012/01/05)

Iron was used as the catalyst for the direct C-H functionalization/C-S bond formation under mild conditions. Various substrates could afford benzothiazoles in moderate to excellent yields. Preliminary mechanistic studies revealed that pyridine played a crucial role for the high yields and selectivities.
