34868-31-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 34868-31-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,4,8,6 and 8 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 34868-31:
(7*3)+(6*4)+(5*8)+(4*6)+(3*8)+(2*3)+(1*1)=140
140 % 10 = 0
So 34868-31-0 is a valid CAS Registry Number.
