1292783-83-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1292783-83-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,9,2,7,8 and 3 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1292783-83:
(9*1)+(8*2)+(7*9)+(6*2)+(5*7)+(4*8)+(3*3)+(2*8)+(1*3)=195
195 % 10 = 5
So 1292783-83-5 is a valid CAS Registry Number.
