Check Digit Verification of cas no

The CAS Registry Mumber 1453867-84-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,5,3,8,6 and 7 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1453867-84:
(9*1)+(8*4)+(7*5)+(6*3)+(5*8)+(4*6)+(3*7)+(2*8)+(1*4)=199
199 % 10 = 9
So 1453867-84-9 is a valid CAS Registry Number.

supporting information, p. 3646 - 3649 (2013/05/21)

Hard core made easy: The pentacyclic core of trichodermatide A was stereoselectively synthesized from a bis(1,3-cyclohexanedione) derivative by a ring-closing reaction followed by an intramolecular ketal formation (see scheme; PPTS=pyridinium p-toluenesulfonate). The first total synthesis of trichodermatide A was then completed by the introduction of three hydroxy groups. Copyright
