108134-67-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 108134-67-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,8,1,3 and 4 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 108134-67:
(8*1)+(7*0)+(6*8)+(5*1)+(4*3)+(3*4)+(2*6)+(1*7)=104
104 % 10 = 4
So 108134-67-4 is a valid CAS Registry Number.
