Check Digit Verification of cas no
The CAS Registry Mumber 940274-21-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,4,0,2,7 and 4 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 940274-21:
(8*9)+(7*4)+(6*0)+(5*2)+(4*7)+(3*4)+(2*2)+(1*1)=155
155 % 10 = 5
So 940274-21-5 is a valid CAS Registry Number.
