162755-97-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 162755-97-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,2,7,5 and 5 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 162755-97:
(8*1)+(7*6)+(6*2)+(5*7)+(4*5)+(3*5)+(2*9)+(1*7)=157
157 % 10 = 7
So 162755-97-7 is a valid CAS Registry Number.
