220906-13-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 220906-13-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,0,9,0 and 6 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 220906-13:
(8*2)+(7*2)+(6*0)+(5*9)+(4*0)+(3*6)+(2*1)+(1*3)=98
98 % 10 = 8
So 220906-13-8 is a valid CAS Registry Number.
