The CAS Registry Mumber 3699-84-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,6,9 and 9 respectively; the second part has 2 digits, 8 and 4 respectively. Calculate Digit Verification of CAS Registry Number 3699-84: (6*3)+(5*6)+(4*9)+(3*9)+(2*8)+(1*4)=131 131 % 10 = 1 So 3699-84-1 is a valid CAS Registry Number.
