549548-34-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 549548-34-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,4,9,5,4 and 8 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 549548-34:
(8*5)+(7*4)+(6*9)+(5*5)+(4*4)+(3*8)+(2*3)+(1*4)=197
197 % 10 = 7
So 549548-34-7 is a valid CAS Registry Number.
