81698-13-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 81698-13-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,6,9 and 8 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 81698-13:
(7*8)+(6*1)+(5*6)+(4*9)+(3*8)+(2*1)+(1*3)=157
157 % 10 = 7
So 81698-13-7 is a valid CAS Registry Number.
