197896-23-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 197896-23-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,7,8,9 and 6 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 197896-23:
(8*1)+(7*9)+(6*7)+(5*8)+(4*9)+(3*6)+(2*2)+(1*3)=214
214 % 10 = 4
So 197896-23-4 is a valid CAS Registry Number.
