Check Digit Verification of cas no

The CAS Registry Mumber 20383-30-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,3,8 and 3 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 20383-30:
(7*2)+(6*0)+(5*3)+(4*8)+(3*3)+(2*3)+(1*0)=76
76 % 10 = 6
So 20383-30-6 is a valid CAS Registry Number.

, p. 987 - 990 (2005)

(Chemical Equation Presented) The complex [Ru(tpy)(pydic)] (1a) is an active catalyst for epoxidation of alkenes by aqueous 30% hydrogen peroxide in tertiary alcohols. The protocol is simple to operate and gives the corresponding epoxides in good to excellent yields. Chiral enantiopure [Ru(tpy*)(pydic) ] complexes have been synthesized and successfully applied in this procedure.
