The CAS Registry Mumber 67756-19-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,7,7,5 and 6 respectively; the second part has 2 digits, 1 and 9 respectively. Calculate Digit Verification of CAS Registry Number 67756-19: (7*6)+(6*7)+(5*7)+(4*5)+(3*6)+(2*1)+(1*9)=168 168 % 10 = 8 So 67756-19-8 is a valid CAS Registry Number.
