Check Digit Verification of cas no

The CAS Registry Mumber 138613-42-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,6,1 and 3 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 138613-42:
(8*1)+(7*3)+(6*8)+(5*6)+(4*1)+(3*3)+(2*4)+(1*2)=130
130 % 10 = 0
So 138613-42-0 is a valid CAS Registry Number.

A facile one-pot stereoselective synthesis of trisubstituted (E)-2-methylalk-2-enoic acids from unactivated Baylis-Hillman adducts and a simple access to some important insect pheromones

Das, Biswanath,Chowdhury, Nikhil,Banerjee, Joydeep,Majhi, Anjoy

, p. 6615 - 6618 (2006)

An efficient one-pot stereoselective synthesis of trisubstituted (E)-2-methylalk-2-enoic acids has been accomplished by treatment of unactivated Baylis-Hillman adducts, 3-hydroxy-2-methylenealkanoates, with Al-NiCl2·6H2O in methanol at room temperature followed by hydrolysis. The method has been applied to the synthesis of three important insect pheromones, (4S,2E)-2,4-dimethyl-2-hexenoic acid, (+)-(S)-manicone and (+)-(S)-normanicone.
