The CAS Registry Mumber 89947-92-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,9,9,4 and 7 respectively; the second part has 2 digits, 9 and 2 respectively. Calculate Digit Verification of CAS Registry Number 89947-92: (7*8)+(6*9)+(5*9)+(4*4)+(3*7)+(2*9)+(1*2)=212 212 % 10 = 2 So 89947-92-2 is a valid CAS Registry Number.
