34667-64-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 34667-64-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,4,6,6 and 7 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 34667-64:
(7*3)+(6*4)+(5*6)+(4*6)+(3*7)+(2*6)+(1*4)=136
136 % 10 = 6
So 34667-64-6 is a valid CAS Registry Number.
