642085-94-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 642085-94-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,4,2,0,8 and 5 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 642085-94:
(8*6)+(7*4)+(6*2)+(5*0)+(4*8)+(3*5)+(2*9)+(1*4)=157
157 % 10 = 7
So 642085-94-7 is a valid CAS Registry Number.
