Check Digit Verification of cas no
The CAS Registry Mumber 78016-85-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,8,0,1 and 6 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 78016-85:
(7*7)+(6*8)+(5*0)+(4*1)+(3*6)+(2*8)+(1*5)=140
140 % 10 = 0
So 78016-85-0 is a valid CAS Registry Number.

Gupta, A. K.,Pant, U. C.
, p. 157 - 158 (2007/10/02)
Six new 8-substituted 2-methyl-1,5-benzothiazepin-4(5H)-ones (IVa-f) have been prepared by the reaction of 5-substituted 2-aminobenzenethiols (I) with ethyl acetoacetate in dry xylene.An improved method for preparing ethyl 3-methyl-4H-1,4-benzothiazine-2-carboxylate (III) is also described.
