The CAS Registry Mumber 23707-18-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,3,7,0 and 7 respectively; the second part has 2 digits, 1 and 8 respectively. Calculate Digit Verification of CAS Registry Number 23707-18: (7*2)+(6*3)+(5*7)+(4*0)+(3*7)+(2*1)+(1*8)=98 98 % 10 = 8 So 23707-18-8 is a valid CAS Registry Number.
