874212-44-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 874212-44-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,7,4,2,1 and 2 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 874212-44:
(8*8)+(7*7)+(6*4)+(5*2)+(4*1)+(3*2)+(2*4)+(1*4)=169
169 % 10 = 9
So 874212-44-9 is a valid CAS Registry Number.
