153887-97-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 153887-97-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,3,8,8 and 7 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 153887-97:
(8*1)+(7*5)+(6*3)+(5*8)+(4*8)+(3*7)+(2*9)+(1*7)=179
179 % 10 = 9
So 153887-97-9 is a valid CAS Registry Number.
