Check Digit Verification of cas no
The CAS Registry Mumber 108262-40-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,8,2,6 and 2 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 108262-40:
(8*1)+(7*0)+(6*8)+(5*2)+(4*6)+(3*2)+(2*4)+(1*0)=104
104 % 10 = 4
So 108262-40-4 is a valid CAS Registry Number.
