Check Digit Verification of cas no
The CAS Registry Mumber 1586819-50-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,5,8,6,8,1 and 9 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1586819-50:
(9*1)+(8*5)+(7*8)+(6*6)+(5*8)+(4*1)+(3*9)+(2*5)+(1*0)=222
222 % 10 = 2
So 1586819-50-2 is a valid CAS Registry Number.
