Check Digit Verification of cas no

The CAS Registry Mumber 139564-97-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,5,6 and 4 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 139564-97:
(8*1)+(7*3)+(6*9)+(5*5)+(4*6)+(3*4)+(2*9)+(1*7)=169
169 % 10 = 9
So 139564-97-9 is a valid CAS Registry Number.

, p. 403 - 406 (2007/10/02)

Reaction of the (3R)-1,5-benzothiazepinon derivative 5 with NaNO2 in glacial acetic acid leads to the rac-1,4-benzothiazinone derivatives 6a and 7.Furthermore, reaction of 5 with NaNO2 in sulphuric acid/KBr yields the ring-contracted compound rac-6b.Compo
