Check Digit Verification of cas no

The CAS Registry Mumber 51221-83-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,1,2,2 and 1 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 51221-83:
(7*5)+(6*1)+(5*2)+(4*2)+(3*1)+(2*8)+(1*3)=81
81 % 10 = 1
So 51221-83-1 is a valid CAS Registry Number.

Selective isomerisation of prop-2-yn-1-ols into α,β-unsaturated aldehydes catalysed by Ru[η3-CH2C(Me)CH2]2(Ph 2PCH2CH2PPh2)

Picquet, Michel,Bruneau, Christian,Dixneuf, Pierre H.

, p. 1201 - 1202 (2007/10/03)

The complex Ru[η3-CH2C(Me)CH2]2(Ph 2PCH2CH2PPh2) is an efficient catalyst precursor for the isomerisation of prop-2-yn-1-ols into conjugated enals under mild conditions in the presence of benzoic acid via (Z)-3-hydroxyprop-1-en-1-yl benzoates.
