872544-83-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 872544-83-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,7,2,5,4 and 4 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 872544-83:
(8*8)+(7*7)+(6*2)+(5*5)+(4*4)+(3*4)+(2*8)+(1*3)=197
197 % 10 = 7
So 872544-83-7 is a valid CAS Registry Number.
