139372-15-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 139372-15-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,3,7 and 2 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 139372-15:
(8*1)+(7*3)+(6*9)+(5*3)+(4*7)+(3*2)+(2*1)+(1*5)=139
139 % 10 = 9
So 139372-15-9 is a valid CAS Registry Number.
