1403891-66-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1403891-66-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,0,3,8,9 and 1 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1403891-66:
(9*1)+(8*4)+(7*0)+(6*3)+(5*8)+(4*9)+(3*1)+(2*6)+(1*6)=156
156 % 10 = 6
So 1403891-66-6 is a valid CAS Registry Number.
