Check Digit Verification of cas no
The CAS Registry Mumber 1401991-17-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,0,1,9,9 and 1 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1401991-17:
(9*1)+(8*4)+(7*0)+(6*1)+(5*9)+(4*9)+(3*1)+(2*1)+(1*7)=140
140 % 10 = 0
So 1401991-17-0 is a valid CAS Registry Number.
