Check Digit Verification of cas no

The CAS Registry Mumber 186963-82-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,6,9,6 and 3 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 186963-82:
(8*1)+(7*8)+(6*6)+(5*9)+(4*6)+(3*3)+(2*8)+(1*2)=196
196 % 10 = 6
So 186963-82-6 is a valid CAS Registry Number.

Synthesis of 3'-difluoromethylene-3'-deoxythymidine and some derivatives

Serafinowski, Pawel J.,Barnes, Colin L.

, p. 225 - 228 (1997)

Ultrasound-assisted reaction of the 3'-oxo derivative of thymidine (1) with bromodifluoromethyl[tris(dimethylamino)phosphonium] bromide (8) and zinc, gives the corresponding 3'-difluoromethylene nucleoside 5. Subsequent removal of the dimethoxytrityl group provides hitherto unreported 3'-difluoromethylene-3'-deoxythymidine (6), a new analogue of AZT.
