906820-20-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 906820-20-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,0,6,8,2 and 0 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 906820-20:
(8*9)+(7*0)+(6*6)+(5*8)+(4*2)+(3*0)+(2*2)+(1*0)=160
160 % 10 = 0
So 906820-20-0 is a valid CAS Registry Number.
