Check Digit Verification of cas no
The CAS Registry Mumber 334543-34-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,3,4,5,4 and 3 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 334543-34:
(8*3)+(7*3)+(6*4)+(5*5)+(4*4)+(3*3)+(2*3)+(1*4)=129
129 % 10 = 9
