The CAS Registry Mumber 640278-13-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,4,0,2,7 and 8 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 640278-13:
(8*6)+(7*4)+(6*0)+(5*2)+(4*7)+(3*8)+(2*1)+(1*3)=143
143 % 10 = 3
So 640278-13-3 is a valid CAS Registry Number.
