Check Digit Verification of cas no

The CAS Registry Mumber 197845-32-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,7,8,4 and 5 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 197845-32:
(8*1)+(7*9)+(6*7)+(5*8)+(4*4)+(3*5)+(2*3)+(1*2)=192
192 % 10 = 2
So 197845-32-2 is a valid CAS Registry Number.

Regioselectivity of the Mannich reaction on pyrrolo[2,3-d]pyrimidine nucleosides related to 7-deaza-2'-deoxyadenosine or 7-deaza-2'-deoxyguanosine

Seela, Frank,Chen, Yaoming,Zulauf, Matthias

, p. 1067 - 1072 (1997)

Mannich reactions were performed on 7-deazapurine 2'-deoxyribonucleosides and the regioselectivity was studied. 7-Deaza-2'-deoxy-adenosine (2'-deoxytubercidin, 4a) furnished the 7-substituted Mannich base 5a. The side chain was introduced in the 8-positio
