Check Digit Verification of cas no

The CAS Registry Mumber 625825-20-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,2,5,8,2 and 5 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 625825-20:
(8*6)+(7*2)+(6*5)+(5*8)+(4*2)+(3*5)+(2*2)+(1*0)=159
159 % 10 = 9
So 625825-20-9 is a valid CAS Registry Number.

Synthesis of 4-alkoxy-4-methyl- and 4-alkoxy-4-fluoromethyl-1,3-benzoxazinones

Alkhathlan, Hamad Z.

, p. 8163 - 8170 (2003)

Cyclization of 2-hydroxyacetophenone hydrazones with triphosgene resulted in the formation of 4-methylene-1,3-benzoxazinones. These compounds were converted to 4-alkoxy-4-methyl-1,3-benzoxazinones and 4-fluoromethyl-4-methoxy-1,3-benzoxazinones upon treatment with alcohols under refluxing conditions and F-TEDA-BF4 in acetonitrile and methanol, respectively.
