39156-93-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 39156-93-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,9,1,5 and 6 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 39156-93:
(7*3)+(6*9)+(5*1)+(4*5)+(3*6)+(2*9)+(1*3)=139
139 % 10 = 9
So 39156-93-9 is a valid CAS Registry Number.
