Check Digit Verification of cas no
The CAS Registry Mumber 111902-57-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,1,9,0 and 2 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 111902-57:
(8*1)+(7*1)+(6*1)+(5*9)+(4*0)+(3*2)+(2*5)+(1*7)=89
89 % 10 = 9
So 111902-57-9 is a valid CAS Registry Number.

Reduction of (6R)-6-amino-6,7-dihydro-2-thienyl-1,4-thiazepin-5(4H)-one derivatives with Mg-MeOH gave the corresponding perhydrothiazepinones.Protection with trityl group at the 6-amino group gave predominantly the 2S,6R isomer which was converted to the
