Check Digit Verification of cas no
The CAS Registry Mumber 219555-90-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,9,5,5 and 5 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 219555-90:
(8*2)+(7*1)+(6*9)+(5*5)+(4*5)+(3*5)+(2*9)+(1*0)=155
