155416-84-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 155416-84-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,5,4,1 and 6 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 155416-84:
(8*1)+(7*5)+(6*5)+(5*4)+(4*1)+(3*6)+(2*8)+(1*4)=135
135 % 10 = 5
