Check Digit Verification of cas no
The CAS Registry Mumber 40492-14-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,0,4,9 and 2 respectively; the second part has 2 digits, 1 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 40492-14:
(7*4)+(6*0)+(5*4)+(4*9)+(3*2)+(2*1)+(1*4)=96
96 % 10 = 6
So 40492-14-6 is a valid CAS Registry Number.
