The CAS Registry Mumber 127759-47-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,7,7,5 and 9 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 127759-47:
(8*1)+(7*2)+(6*7)+(5*7)+(4*5)+(3*9)+(2*4)+(1*7)=161
161 % 10 = 1
So 127759-47-1 is a valid CAS Registry Number.
