59742-40-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 59742-40-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,9,7,4 and 2 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 59742-40:
(7*5)+(6*9)+(5*7)+(4*4)+(3*2)+(2*4)+(1*0)=154
154 % 10 = 4
So 59742-40-4 is a valid CAS Registry Number.
