68570-33-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 68570-33-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,8,5,7 and 0 respectively; the second part has 2 digits, 3 and 3 respectively.Calculate Digit Verification of CAS Registry Number 68570-33:
(7*6)+(6*8)+(5*5)+(4*7)+(3*0)+(2*3)+(1*3)=152
152 % 10 = 2
So 68570-33-2 is a valid CAS Registry Number.
