634598-09-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 634598-09-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,3,4,5,9 and 8 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 634598-09:
(8*6)+(7*3)+(6*4)+(5*5)+(4*9)+(3*8)+(2*0)+(1*9)=187
187 % 10 = 7
So 634598-09-7 is a valid CAS Registry Number.
