1067642-75-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1067642-75-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,6,7,6,4 and 2 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1067642-75:
(9*1)+(8*0)+(7*6)+(6*7)+(5*6)+(4*4)+(3*2)+(2*7)+(1*5)=164
164 % 10 = 4
So 1067642-75-4 is a valid CAS Registry Number.
