142608-07-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 142608-07-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,2,6,0 and 8 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 142608-07:
(8*1)+(7*4)+(6*2)+(5*6)+(4*0)+(3*8)+(2*0)+(1*7)=109
109 % 10 = 9
So 142608-07-9 is a valid CAS Registry Number.
