The CAS Registry Mumber 6990-76-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,9,9 and 0 respectively; the second part has 2 digits, 7 and 6 respectively. Calculate Digit Verification of CAS Registry Number 6990-76: (6*6)+(5*9)+(4*9)+(3*0)+(2*7)+(1*6)=137 137 % 10 = 7 So 6990-76-7 is a valid CAS Registry Number.
