The CAS Registry Mumber 391278-03-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,9,1,2,7 and 8 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 391278-03:
(8*3)+(7*9)+(6*1)+(5*2)+(4*7)+(3*8)+(2*0)+(1*3)=158
158 % 10 = 8
So 391278-03-8 is a valid CAS Registry Number.
