The CAS Registry Mumber 138128-29-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,1,2 and 8 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 138128-29:
(8*1)+(7*3)+(6*8)+(5*1)+(4*2)+(3*8)+(2*2)+(1*9)=127
127 % 10 = 7
So 138128-29-7 is a valid CAS Registry Number.

2α-Methylhopanoids: First recognition in the bacterium Methylbacterium organophilum and obtention via sulphur induced isomerization of 2β-methylhopanoids. An account for their presence in sediments

Stampf,Herrmann,Bisseret,Rohmer

, p. 7081 - 7090 (1991)

First recognition of 2α-methyldiplopterol from the bacterium Methylbacterium organophilum and sulphur induced isomerization of 2β-methylhopanoids into their 2α-methyl isomers suggest a dual origin for the sedimentary 2α-methylhopanoids.
