85644-03-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 85644-03-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,5,6,4 and 4 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 85644-03:
(7*8)+(6*5)+(5*6)+(4*4)+(3*4)+(2*0)+(1*3)=147
147 % 10 = 7
So 85644-03-7 is a valid CAS Registry Number.
