193279-87-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 193279-87-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,3,2,7 and 9 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 193279-87:
(8*1)+(7*9)+(6*3)+(5*2)+(4*7)+(3*9)+(2*8)+(1*7)=177
177 % 10 = 7
So 193279-87-7 is a valid CAS Registry Number.
