Check Digit Verification of cas no
The CAS Registry Mumber 109948-32-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,9,9,4 and 8 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 109948-32:
(8*1)+(7*0)+(6*9)+(5*9)+(4*4)+(3*8)+(2*3)+(1*2)=155
155 % 10 = 5
So 109948-32-5 is a valid CAS Registry Number.
