34280-38-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 34280-38-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,4,2,8 and 0 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 34280-38:
(7*3)+(6*4)+(5*2)+(4*8)+(3*0)+(2*3)+(1*8)=101
101 % 10 = 1
So 34280-38-1 is a valid CAS Registry Number.
