Check Digit Verification of cas no
The CAS Registry Mumber 206130-75-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,6,1,3 and 0 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 206130-75:
(8*2)+(7*0)+(6*6)+(5*1)+(4*3)+(3*0)+(2*7)+(1*5)=88
88 % 10 = 8
So 206130-75-8 is a valid CAS Registry Number.
