871002-42-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 871002-42-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,7,1,0,0 and 2 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 871002-42:
(8*8)+(7*7)+(6*1)+(5*0)+(4*0)+(3*2)+(2*4)+(1*2)=135
135 % 10 = 5
