928821-35-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 928821-35-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,2,8,8,2 and 1 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 928821-35:
(8*9)+(7*2)+(6*8)+(5*8)+(4*2)+(3*1)+(2*3)+(1*5)=196
196 % 10 = 6
So 928821-35-6 is a valid CAS Registry Number.
