The CAS Registry Mumber 649552-53-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,4,9,5,5 and 2 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 649552-53:
(8*6)+(7*4)+(6*9)+(5*5)+(4*5)+(3*2)+(2*5)+(1*3)=194
194 % 10 = 4
