Check Digit Verification of cas no
The CAS Registry Mumber 140899-21-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,0,8,9 and 9 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 140899-21:
(8*1)+(7*4)+(6*0)+(5*8)+(4*9)+(3*9)+(2*2)+(1*1)=144
144 % 10 = 4
So 140899-21-4 is a valid CAS Registry Number.
