The CAS Registry Mumber 137245-64-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,7,2,4 and 5 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 137245-64:
(8*1)+(7*3)+(6*7)+(5*2)+(4*4)+(3*5)+(2*6)+(1*4)=128
128 % 10 = 8
So 137245-64-8 is a valid CAS Registry Number.
