141622-31-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 141622-31-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,1,6,2 and 2 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 141622-31:
(8*1)+(7*4)+(6*1)+(5*6)+(4*2)+(3*2)+(2*3)+(1*1)=93
93 % 10 = 3
So 141622-31-3 is a valid CAS Registry Number.
