Check Digit Verification of cas no

The CAS Registry Mumber 137140-13-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,7,1,4 and 0 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 137140-13:
(8*1)+(7*3)+(6*7)+(5*1)+(4*4)+(3*0)+(2*1)+(1*3)=97
97 % 10 = 7
So 137140-13-7 is a valid CAS Registry Number.

Iron-osmium bonding in clusters containing ferrocene fragments

Cullen, William R.,Rettig, Steven J.,Zheng, Tu-Cai

, p. 277 - 283 (1992)

Pyrolysis of Os3(CO)10(PFcPh2)2 and Os3(CO)11(PFc2Ph) affords Os3(CO)8(H)2[PAr(C6H 5)(η-C5H3)Fe-(η-C5H 4)] (Ar = C6H5 (3a), Fc (3b), respectively). Os3(CO)7(H)(PPri)[Fe(η-C5H 4PPri2)(η-C5H4)] (4) is a product of the thermolysis of Os3(CO)10[Fe(η-C5H4PPr i2)2]. 3b: triclinic, space group P1 (No. 2), a = 13.878 (2) A?, b = 14.145 (3) A?, c = 10.698 (2) A?, α = 104.28 (1)°, β = 110.88 (1)°, γ = 63.91 (1)°. 3a: monoclinic, space group P21/c (No. 14), a = 9.484 (3) A?, b = 18.144 (4) A?, c = 17.421 (3) A?, β = 90.10 (2)°. 4: monoclinic, space group P21/n (No. 14), a = 8.910 (3) A?, b = 22.784 (2) A?, c = 15.416 (2) A?, β = 98.25 (2)°. The complexes are electron precise if the Fe→Os bonds of length 2.830 (1) (3a), 2.826 (1) (3b), and 2.813 (1) A? (4) are included.
