156209-22-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 156209-22-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,6,2,0 and 9 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 156209-22:
(8*1)+(7*5)+(6*6)+(5*2)+(4*0)+(3*9)+(2*2)+(1*2)=122
122 % 10 = 2
So 156209-22-2 is a valid CAS Registry Number.
