Check Digit Verification of cas no
The CAS Registry Mumber 78308-03-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,8,3,0 and 8 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 78308-03:
(7*7)+(6*8)+(5*3)+(4*0)+(3*8)+(2*0)+(1*3)=139
139 % 10 = 9
