Check Digit Verification of cas no
The CAS Registry Mumber 25809-98-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,5,8,0 and 9 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 25809-98:
(7*2)+(6*5)+(5*8)+(4*0)+(3*9)+(2*9)+(1*8)=137
137 % 10 = 7
