164215-22-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 164215-22-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,4,2,1 and 5 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 164215-22:
(8*1)+(7*6)+(6*4)+(5*2)+(4*1)+(3*5)+(2*2)+(1*2)=109
109 % 10 = 9
So 164215-22-9 is a valid CAS Registry Number.
