Check Digit Verification of cas no

The CAS Registry Mumber 67204-23-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,7,2,0 and 4 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 67204-23:
(7*6)+(6*7)+(5*2)+(4*0)+(3*4)+(2*2)+(1*3)=113
113 % 10 = 3
So 67204-23-3 is a valid CAS Registry Number.

Unusually weak metal-hydrogen bonds in HV(CO)4(P-P) and their effectiveness as H? donors

Choi, Jongwook,Pulling, Mary E.,Smith, Deborah M.,Norton, Jack R.

, p. 4250 - 4252 (2008)

The V-H bonds in HV(CO)4(P-P) are unusually weak (55 to 58 kcal/mol). They transfer H? to styrene more rapidly than CpCr(CO)3H does and are effective stoichiometric reagents for the cyclization of appropriate 1,6-dienes. C
