The CAS Registry Mumber 137769-65-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,7,7,6 and 9 respectively; the second part has 2 digits, 6 and 5 respectively. Calculate Digit Verification of CAS Registry Number 137769-65: (8*1)+(7*3)+(6*7)+(5*7)+(4*6)+(3*9)+(2*6)+(1*5)=174 174 % 10 = 4 So 137769-65-4 is a valid CAS Registry Number.
