Check Digit Verification of cas no
The CAS Registry Mumber 380631-06-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,8,0,6,3 and 1 respectively; the second part has 2 digits, 0 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 380631-06:
(8*3)+(7*8)+(6*0)+(5*6)+(4*3)+(3*1)+(2*0)+(1*6)=131
131 % 10 = 1
So 380631-06-1 is a valid CAS Registry Number.
