Check Digit Verification of cas no

The CAS Registry Mumber 690244-72-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,9,0,2,4 and 4 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 690244-72:
(8*6)+(7*9)+(6*0)+(5*2)+(4*4)+(3*4)+(2*7)+(1*2)=165
165 % 10 = 5
So 690244-72-5 is a valid CAS Registry Number.

Betuligenol derivative with growth inhibition and antifeedant activity

Chattopadhyay, Sunil K.,Srivastava, Sachin,Sashidhara, Koneni V.,Tripathi, Arun K.,Bhattacharya, Asish K.,Negi, Arvind S.

, p. 1729 - 1731 (2007/10/03)

The title chiral amine, 3-(4-methoxyphenyl)-1-methylpropylamine 5 has been synthesized from naturally abundant betuligenol 1 in three steps and also in good yield. Furthermore, the versatile intermediate 3 could be manipulated for the preparation of chiral disulphide 7. The amine derivative 5 prepared from (-)-betuligenol showed significant growth inhibition and antifeedant activity.
