The CAS Registry Mumber 135761-19-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,5,7,6 and 1 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 135761-19:
(8*1)+(7*3)+(6*5)+(5*7)+(4*6)+(3*1)+(2*1)+(1*9)=132
132 % 10 = 2
So 135761-19-2 is a valid CAS Registry Number.
