116274-20-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 116274-20-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,6,2,7 and 4 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 116274-20:
(8*1)+(7*1)+(6*6)+(5*2)+(4*7)+(3*4)+(2*2)+(1*0)=105
105 % 10 = 5
So 116274-20-5 is a valid CAS Registry Number.
