207738-63-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 207738-63-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,7,7,3 and 8 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 207738-63:
(8*2)+(7*0)+(6*7)+(5*7)+(4*3)+(3*8)+(2*6)+(1*3)=144
144 % 10 = 4
So 207738-63-4 is a valid CAS Registry Number.
