638222-80-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 638222-80-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,3,8,2,2 and 2 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 638222-80:
(8*6)+(7*3)+(6*8)+(5*2)+(4*2)+(3*2)+(2*8)+(1*0)=157
157 % 10 = 7
So 638222-80-7 is a valid CAS Registry Number.
