223689-35-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 223689-35-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,3,6,8 and 9 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 223689-35:
(8*2)+(7*2)+(6*3)+(5*6)+(4*8)+(3*9)+(2*3)+(1*5)=148
148 % 10 = 8
So 223689-35-8 is a valid CAS Registry Number.
