154138-77-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 154138-77-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,4,1,3 and 8 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 154138-77:
(8*1)+(7*5)+(6*4)+(5*1)+(4*3)+(3*8)+(2*7)+(1*7)=129
129 % 10 = 9
So 154138-77-9 is a valid CAS Registry Number.
