Check Digit Verification of cas no
The CAS Registry Mumber 1240244-40-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,4,0,2,4 and 4 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1240244-40:
(9*1)+(8*2)+(7*4)+(6*0)+(5*2)+(4*4)+(3*4)+(2*4)+(1*0)=99
99 % 10 = 9
So 1240244-40-9 is a valid CAS Registry Number.
