Check Digit Verification of cas no

The CAS Registry Mumber 218129-87-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,8,1,2 and 9 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 218129-87:
(8*2)+(7*1)+(6*8)+(5*1)+(4*2)+(3*9)+(2*8)+(1*7)=134
134 % 10 = 4
So 218129-87-4 is a valid CAS Registry Number.

Studies on the substituted 3-aminopropan-1-ol motif of lycoctonine class norditerpenid alkaloids: A novel route to 3-hydroxymethylcyclohex-2-enone

Doisy, Xavier,Blagbrough, Ian S.,Thomas, Noel F.,Potter, Barry V. L.

, p. 8525 - 8528 (2007/10/03)

Pursuing our interest in methyllcaconitine (MLA), we have designed a synthetic route to substituted ring-A of lycoctonine class norditerpenoid alkaloids. A novel synthesis of 3-hydroxymethylcyclohex-2-enone has been achieved starting from cyclohex-2-enone. Key reactions are: 1,2-addition of 1,3-dithiane followed by allylic rearrangement, 1,4-hydrocyanation, Wittig reaction and conversion into the substituted N-ethyl-3-aminopropan-1-ol motif of these neopentyl-like alcohols.
