31106-67-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 31106-67-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,1,1,0 and 6 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 31106-67:
(7*3)+(6*1)+(5*1)+(4*0)+(3*6)+(2*6)+(1*7)=69
69 % 10 = 9
So 31106-67-9 is a valid CAS Registry Number.
