Check Digit Verification of cas no

The CAS Registry Mumber 180746-45-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,0,7,4 and 6 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 180746-45:
(8*1)+(7*8)+(6*0)+(5*7)+(4*4)+(3*6)+(2*4)+(1*5)=146
146 % 10 = 6
So 180746-45-6 is a valid CAS Registry Number.

, p. 516 - 522 (1996)

6-Amino-thiopyran-2-thiones (1) react with dihydrogen sulfide in the presence of pyridine and triethyl amine to yield 6-thioxo-thiopyran-2-thiolates (2). Methylation of 2 gives the methylthio compounds 3 and 4. Further methylation of 3a and 4a yields the
