Check Digit Verification of cas no
The CAS Registry Mumber 117648-95-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,7,6,4 and 8 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 117648-95:
(8*1)+(7*1)+(6*7)+(5*6)+(4*4)+(3*8)+(2*9)+(1*5)=150
150 % 10 = 0
So 117648-95-0 is a valid CAS Registry Number.
