1619986-32-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1619986-32-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,1,9,9,8 and 6 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1619986-32:
(9*1)+(8*6)+(7*1)+(6*9)+(5*9)+(4*8)+(3*6)+(2*3)+(1*2)=221
221 % 10 = 1
So 1619986-32-1 is a valid CAS Registry Number.
