642969-59-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 642969-59-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,4,2,9,6 and 9 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 642969-59:
(8*6)+(7*4)+(6*2)+(5*9)+(4*6)+(3*9)+(2*5)+(1*9)=203
203 % 10 = 3
So 642969-59-3 is a valid CAS Registry Number.
