The CAS Registry Mumber 617705-50-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,1,7,7,0 and 5 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 617705-50:
(8*6)+(7*1)+(6*7)+(5*7)+(4*0)+(3*5)+(2*5)+(1*0)=157
157 % 10 = 7
So 617705-50-7 is a valid CAS Registry Number.
