87689-23-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 87689-23-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,7,6,8 and 9 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 87689-23:
(7*8)+(6*7)+(5*6)+(4*8)+(3*9)+(2*2)+(1*3)=194
194 % 10 = 4
So 87689-23-4 is a valid CAS Registry Number.
