Check Digit Verification of cas no

The CAS Registry Mumber 1276124-75-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,7,6,1,2 and 4 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1276124-75:
(9*1)+(8*2)+(7*7)+(6*6)+(5*1)+(4*2)+(3*4)+(2*7)+(1*5)=154
154 % 10 = 4
So 1276124-75-4 is a valid CAS Registry Number.

Stable iso-osmabenzenes from a formal [3+3] cycloaddition reaction of metal vinylidene with alkynols

Zhao, Qianyi,Gong, Lei,Xu, Chunfa,Zhu, Jun,He, Xumin,Xia, Haiping

, p. 1354 - 1358 (2011)

The magic of Os: An unprecedented formal [3+3] cycloaddition reaction of 1 with alkynols affords stable iso-osmabenzenes at room temperature (see scheme). The phosphonium substituent at the Cβ position and the 18e - nature of the compound play key roles in the origin of the high thermal stability of the products. Isomerization of iso-osmabenzenes into η5-cyclopentadienyl complexes through metalated cyclopentadiene intermediates is also described.
