Check Digit Verification of cas no

The CAS Registry Mumber 34155-83-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,4,1,5 and 5 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 34155-83:
(7*3)+(6*4)+(5*1)+(4*5)+(3*5)+(2*8)+(1*3)=104
104 % 10 = 4
So 34155-83-4 is a valid CAS Registry Number.

A New Synthesis of Some Naturally Occurring Acetylchromenes

Ahluwalia, V. K.,Arora, K. K.,Manchanda, Saroj

, p. 1039 - 1040 (2007/10/02)

Acetovanillochromene (1) has been synthesized by the nuclear isoprenylation of 4-hydroxy-3-methoxyacetophenone (4) followed by dehydrogenation of the chromane (5), thus formed.Similarly, 6-acetyl-5-hydroxy-8-methoxy-2,2-dimethyl-2H-1-benzopyran (2) and its methyl ether (3) have also been synthesized.All the three chromenes (1 - 3) are naturally occurring.
