Check Digit Verification of cas no

The CAS Registry Mumber 85615-02-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,5,6,1 and 5 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 85615-02:
(7*8)+(6*5)+(5*6)+(4*1)+(3*5)+(2*0)+(1*2)=137
137 % 10 = 7
So 85615-02-7 is a valid CAS Registry Number.

Acid Catalyzed Condensation of Isoprene with Orcinol: Synthesis of 2,2-Dimethylchromans and 5-Methylxanthyletin Derivatives

Ahluwalia, Vinod K.,Khanna, Manjula,Singh, Rishi P.

, p. 71 - 77 (1983)

Condensation of orcinol with 2-methylbuta-1,3-diene (isoprene) has been achieved in the presence of orthophosphoric acid as catalyst leading to the exclusive formation of 2,2-dimethylchromans in one step.A novel route for the synthesis of 5-methylxanthyletin derivatives is described. - Keywords: 2,3-Dichloro-5,6-dicyano-1,4-benzoquinone; 2,2-Dimethylchromans; 2-Methylbuta-1,3-diene; 5-Methylxanthyletin; Orcinol; Pechmann condensation
