141869-22-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 141869-22-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,1,8,6 and 9 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 141869-22:
(8*1)+(7*4)+(6*1)+(5*8)+(4*6)+(3*9)+(2*2)+(1*2)=139
139 % 10 = 9
So 141869-22-9 is a valid CAS Registry Number.
