Check Digit Verification of cas no
The CAS Registry Mumber 212003-47-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,2,0,0 and 3 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 212003-47:
(8*2)+(7*1)+(6*2)+(5*0)+(4*0)+(3*3)+(2*4)+(1*7)=59
59 % 10 = 9
So 212003-47-9 is a valid CAS Registry Number.

Nickel-catalyzed generation of 2-methylhex-5-enyl ethers from allyl ethers with trimethylaluminium
Taniguchi, Takahiko,Ogasawara, Kunio
, p. 1531 - 1532 (2007/10/03)
Allyl ethers have been converted into the corresponding 2-methylhex-5-enyl ethers in one step on treatment with trimethylaluminium in the presence of a catalytic amount of (dppp)NiCl2.
