109758-31-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 109758-31-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,9,7,5 and 8 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 109758-31:
(8*1)+(7*0)+(6*9)+(5*7)+(4*5)+(3*8)+(2*3)+(1*1)=148
148 % 10 = 8
So 109758-31-8 is a valid CAS Registry Number.
