Check Digit Verification of cas no
The CAS Registry Mumber 153887-99-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,3,8,8 and 7 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 153887-99:
(8*1)+(7*5)+(6*3)+(5*8)+(4*8)+(3*7)+(2*9)+(1*9)=181
181 % 10 = 1
