Check Digit Verification of cas no
The CAS Registry Mumber 6304-46-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,3,0 and 4 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 6304-46:
(6*6)+(5*3)+(4*0)+(3*4)+(2*4)+(1*6)=77
77 % 10 = 7
