Check Digit Verification of cas no
The CAS Registry Mumber 187806-29-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,7,8,0 and 6 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 187806-29:
(8*1)+(7*8)+(6*7)+(5*8)+(4*0)+(3*6)+(2*2)+(1*9)=177
177 % 10 = 7
So 187806-29-7 is a valid CAS Registry Number.

Novel tocopherol compounds I. Bromination of α-tocopherol-reaction mechanism and synthetic applications
Rosenau,Habicher
, p. 7919 - 7926 (1995)
Bromination of α-tocopherol is shown to proceed as a two-step process including the occurrence of an ortho-quinone methide, not as a radical-chain reaction, contrary to earlier reports. The ortho-quinone methide intermediate is also produced by oxidation
