The CAS Registry Mumber 61968-47-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,1,9,6 and 8 respectively; the second part has 2 digits, 4 and 7 respectively.Calculate Digit Verification of CAS Registry Number 61968-47:
(7*6)+(6*1)+(5*9)+(4*6)+(3*8)+(2*4)+(1*7)=156
156 % 10 = 6
So 61968-47-6 is a valid CAS Registry Number.
