117620-31-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 117620-31-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,7,6,2 and 0 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 117620-31:
(8*1)+(7*1)+(6*7)+(5*6)+(4*2)+(3*0)+(2*3)+(1*1)=102
102 % 10 = 2
So 117620-31-2 is a valid CAS Registry Number.
