Check Digit Verification of cas no

The CAS Registry Mumber 197781-21-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,7,7,8 and 1 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 197781-21:
(8*1)+(7*9)+(6*7)+(5*7)+(4*8)+(3*1)+(2*2)+(1*1)=188
188 % 10 = 8
So 197781-21-8 is a valid CAS Registry Number.

Monomethylated 3-thiacyclopentylsulfamic acids and their quality of sweetness

Unterhalt,Kerckhoff,Mollers

, p. 101 - 108 (2000)

Methyl-3-thiacyclopentanamines 4a-c were reacted to their sulfamic acid sodium salts 5a-c, and their structures determined. Only sodium 4-methyl-3- thiacyclopentylsulfamate (5b) is sweet. The oxa analogues 8a-b however are tasteless.
