92020-64-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 92020-64-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,2,0,2 and 0 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 92020-64:
(7*9)+(6*2)+(5*0)+(4*2)+(3*0)+(2*6)+(1*4)=99
99 % 10 = 9
So 92020-64-9 is a valid CAS Registry Number.
