Check Digit Verification of cas no

The CAS Registry Mumber 251918-41-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,5,1,9,1 and 8 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 251918-41:
(8*2)+(7*5)+(6*1)+(5*9)+(4*1)+(3*8)+(2*4)+(1*1)=139
139 % 10 = 9
So 251918-41-9 is a valid CAS Registry Number.

Condensed-purines syntheses of tetrahydro-1,4-diazepino[1,2,3-gh]purin- 2-one and hexahydro-1,4-diazocino[1,2,3-gh]purin-2-one

Suzuki, Hirokazu,Sawanishi, Hiroyuki,Yamamoto, Kenji,Miyamoto, Ken-Ichi

, p. 1322 - 1325 (2007/10/03)

1,4-Pyrimido- (2a), 1,4-diazepino- (2b), and 1,4-diazocino[1,2,3- gh]purine (2c) were designed as selective cAMP-phosphodiesterase 4 (PDE 4) inhibitors. The desired condensed-purines (2b,c) were synthesized by reaction of 7-aminoalkyl-3-propylpurine-2,4-d
