638203-79-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 638203-79-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,3,8,2,0 and 3 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 638203-79:
(8*6)+(7*3)+(6*8)+(5*2)+(4*0)+(3*3)+(2*7)+(1*9)=159
159 % 10 = 9
So 638203-79-9 is a valid CAS Registry Number.
