197964-95-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 197964-95-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,7,9,6 and 4 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 197964-95:
(8*1)+(7*9)+(6*7)+(5*9)+(4*6)+(3*4)+(2*9)+(1*5)=217
217 % 10 = 7
So 197964-95-7 is a valid CAS Registry Number.
